Seed starting chronicles 2012

Submitted by Tim Ingram on Thu, 01/19/2012 - 13:42

Looking back over the 2011 thread is very stimulating. We sowed quite a bit of home collected seed last autumn and this is mostly outside in a cold frame; germination probably won't occur for a couple of months, though our mlld winter so far may not be sufficient to provide the stratification that is necessary for some plants. I am now going through seed from Alplains, Holubec and other collectors, and the seed exchanges to divide it into groups requiring different conditions. Quite a bit will go into the fridge after sowing for 6 to 8 weeks. We have sown other seed that needs no cold treatment in a propagator in the greenhouse but the lower light levels in the winter do lead to etiolation in some species (though not all). Great way of spending a winter's day...

Agreed!! ;D I plan on sowing seed today from the American Primrose society exchange and putting them under the growlights indoors. My NARGS seed haven't arrived yet, so I need to save space for them, which will be a struggle as there is only so much space under the lights and always way too many seeds to sow!

Euphorbia rigida - sown in greenhouse, germinated rapidly (seed had been stored for 7 years so very pleasing to get good germination)
Lesquerella intermedia & fendleri (SWNS)
Stachys coccinea (SWNS)
Chilopsis linearis (SWNS)
Erysimum wheeleri (SWNS) - all these sown with bottom heat in greenhouse
(there are also several yuccas germinating as above from 10/11 year old seed from Ron Ratko, and a couple of dudleya of similar age)
Lupinus versicolor - sown as the Euphorbia after chipping seed
Lomatium utriculatum - home saved seed sown outside in a cold frame (hadn't expected such rapid germination)

(I now have to remove the food from our fridge in the garage to make room for all the pots sown this January!)

Tim, so glad you started this 2012 topic, one of my favs for sure.  And thanks for making your photo large enough to see it full size to see all those perky seedlings and read the plant labels.  Good crop of southwesterners coming up there.  I've always wanted to try growing Desert Willow (Chilopsis linearis); but I don't think it could survive our New England climate.  It is rated zone 7-10, and for some smaller plants I will sometimes try "pushing the hardiness envelope" a bit, but my few attempts at doing that with shrubs (like Cistus, some maples) have failed, the winter cold is just too much for them.  In a few (very few) cases, I've had some luck with southwestern shrubbies, one of my favorites is Philadelphus microphyllus from SWNS a number of years ago, and perfectly hardy.

Tim, did these all (except the Erysimum) germinate at room temperature?

And except for the mentioned chipping, was there any pretreatment?

Any tips for sowing/germinating Geranium fremontii? I came across a mention of scarification and a 24 hour soak, which I have not heard of for other Geraniums??


Submitted by Lori S. on Sat, 01/21/2012 - 02:15

It seemed like unusual advice to me too, Cohan, but I was surprised to see that scarification is recommended in the Alplains catalogue for G. viscosissimum (after which just the usual 70-degree-ish conditions are recommended, if I'm remembering the meaning of the codes correctly).  

I had to look that species up.  This article suggests that "Geranium fremontii" may be more correctly known as G. caespitosum, and that  fremontii may be just a variety, which USDA Plants seems to agree with.
http://www.swcoloradowildflowers.com/Pink%20Enlarged%20Photo%20Pages/ger...
http://plants.usda.gov/java/profile?symbol=GECAF

The 24 hour soak recommendation is still odd, though.  Dr. Deno's work (First Supplement to the Second Edition of Seed Germination Theory and Practice) doesn't support it.  He reports that pre-soaking prior to germinating in moist conditions either did not give significantly faster germination, or actually risked seed death by inhibiting its access to oxygen and causing asphyxiation.  I know it's something some people like to do, however.


Submitted by Tim Ingram on Sat, 01/21/2012 - 03:38

I have sometimes tried chipping geranium seed and think it can be effective, especially if you only have a few seed of something really special. I've not soaked them but normally just sit seed pots in water overnight which is likely to imbibe the seed pretty well. (When I was working in science I was chastised for watering all the freshly sown seed of Sweet Peas being used in genetic studies of their flowering - I was looking after the greenhouse over the weekend! - I have been very wary of soaking legume seed for too long ever since!).

Rick - all these seed except the Lomatium and Euphorbia were started off with bottom heat in the greenhouse - I suppose equivalent to 'room temperatures' and then removed to the lightest spot in the greenhouse once germinated. So they will now experience quite warm days and cool nights and I am not too keen that they grow too quickly! (probably should have sown some of them rather later in the spring but there is always too much to do then).

With respect to Geranium viscosissimum, I have had excellent success using a couple methods. Scarifying the seeds between folds of 100-grit sandpaper and exposing  them to conventional (warm, moist, and well-illuminated) growing conditions resulted in 80% germination within two weeks. I achieved comparable germination by enclosing the seeds in a foil packet and submerging them in boiling water for 10 seconds, exposing them to 8 weeks of cold-moist stratification, than transferring them to a warm environment. Germination began during the cold treatment and continued during the warm phase. I'd guess that the cold treatment was unnecessary for this species, but it did no damage. Failure to scarify, or to expose the seeds to a longer period of boiling water, resulted in no germination. Alternatively, direct seeding (also known as neglecting to deadhead) resulted in many seedlings in the garden.


Submitted by Peter George on Sat, 01/21/2012 - 09:10

Now why would 'direct seeding' result in a high germination rate when there was neither scarification nor the boiling water treatment? I know nature is always 'right,' but what is it about plants just dropping seeds that makes the germination rates so high when if we do the same thing, we get nothing?

Not to imply that the conditions are the same, but it's interesting that Bob Nold grows it in Denver, far from the Sonoran and Chihuahuan desert washes that I tend to associate it with from fondly-remembered trips long ago (re. High and Dry: Gardening with Cold-hardy Dryland Plants).  I hope this mention of his name will get his spider senses tingling, so he can pop in and tell us about it in person!

Tim, you have a great start to the season.  I've started earlier than usual this year, but only have 4 pots of sprouts so far - eager beavers that need nothing more than scarification or just moisture to trigger them:  Astragalus coccineus (so easy to germinate, so hard to grow!!), Oxytropis lagopus, Acantholimon saxifragiformeSalvia pachyphylla also germinated in a few days, which kind of surprises me.

I assume that the hard seed coat prevents too-early germination (read: autumn) in G. viscosissimum.

I regret that I had no difficulty in killing Chilopsis linearis a few years ago. But that record-setting cold snap--4 days of lows near -10 C in early October, which constituted the first frost of the year--took out quite a few marginally hardy plants (including all of our cactus).


Submitted by cohan on Sat, 01/21/2012 - 19:27

I also don't see why direct garden seeding results in germination without scarification ( I could see if it was just a matter of much larger numbers of seed and low germination percentages).. I suppose the sown seeds that were not scarified and did not germinate were just given cold stratification without freezing? So then maybe outdoor treatment over winter would work without scarfication? I have to see how many seeds I have, whether or not there are enough to experiment....
Lori, I did also gather from googling that fremontii is considered by some to be a sub-species of caespitosum.. Ironically, the seed for this North American came to me from Philippe in France...lol

Remember too, that we really don't know how old germinating seeds are that were naturally dispersed.  Given enough time in the natural environment, the breakdown of the seed coat an subsequent germination might not be so vexing after all.

I'm hoping Philippe would know better since seed comes from the botanic garden..lol-- though mistakes can happen anywhere! In fact any Geranium is okay if its pink, or even white, or any colour other than that neon blue-purple of himalayense which we have many many square meters of....  :-X

I wanted to add that a friend in Nebraska successfully grew Chilopsis linearis a for a couple of years, from AZ seed (I think it was just seed gathered around metro Phoenix by another friend)- if I recall the sequence of events, he had it planted in ground, and mulched heavily the first winter; if died back to the mulch, but grew several feet or more next season and flowered; second winter he was not well enough to mulch and the plant died.. I forget what his lows were, but I could ask if anyone would like to know..

It is the strategy of the plant! When seeds are ripe or almost so before late fall it can be beneficial for the species that some seed sprout immediately if it is moist enough. A little later the seeds have gone into a dormancy which is hard to break and not all germinate the next season either but need more than one season to break dormancy. This is often the case with seed from plants where the seasons can be a little unpredictable and the plant build up a kind of seedbank in the soil.

Many of the easy ones are sprouting now. 
I started some very old seeds of Ipomoea leptophylla, and in two days, after strenuous filing of the very hard seeds, the sprouts are practically heaving the soil out of the pot!
Smelowskia calycina is an eager sprouter; the first germination was after 2 days, and lots are up after 4 days.
It's the same with Arenaria pseudoacantholimon, Silene nigrescens and Gastrolychnis apetala!


Submitted by Tim Ingram on Thu, 01/26/2012 - 02:10

Lori - I am trying Ipomaea leptophylla and Silene nigrescens too, both germinating well. I assume you sow under artificial light?
For me both of these are etiolating considerably (although other seedlings are not) and I think I need to give them much higher light intensities, or possibly prolonged daylength?


Submitted by Lori S. on Thu, 01/26/2012 - 06:28

Yes, I start most seeds indoors under fluorescent lights - each shelf of the plant stand has two double-light ballasts.  I'll have to check the wattage of the bulbs (can't remember).  Some are stratified in the cold room then brought out to the plant stand for germination, or after they germinate in the cold room. Alpines tend to grow a little looser than they should in my setup, but may tighten up after they are planted outdoors, so I don't see this as a huge problem, usually, though more intense light would certainly always be an improvement.  I think the permanent growing conditions may be more important overall to the plants ending up with the desired small, tight forms that we expect or hope for... ??  (See: http://nargs.org/smf/index.php?topic=317.0 )  We did use very high intensity metal halide lighting at one time (for wintering-over water lilies and tropicals, mainly) but it was pretty unpleasant to be around - I imagine there have probably been improvements to these sorts of set ups now.  Starting them outside here doesn't give any particular advantage (in my opinion) in terms of getting seedlings to a good size prior to planting out, which I like to do as soon as possible. (I don't usually have the patience to take care of seedling pots for extended periods of time.)

NB.  Edited to add details.  This isn't meant to be taken as a recommendation to anyone - it's just a description of how I've been doing things, and needless to say, there is lots of room for improvement to it!!  :o


Submitted by mkyoung on Thu, 01/26/2012 - 07:27

Lori, thanks for the welcome.  I've grown around 1000 species in the garden here, not to say that all or even most of them are still with me. I'm particularly fond of species from the U.S. Southwest, particularly penstemons. Given the tendency for this part of Montana to have rain and -20 to -30 C nights each winter, many of these plants are grown, unintentionally, as annuals. Or were grown; I subscribe to the notion that after killing a species three times, one can declare victory and move on to others. Thus Chilopsis linearis has two more chances. Lauren Springer profiled a reputedly hardier cultivar in her revised edition of The Undaunted Garden, so I know my next victim.

I started my one-hundred-ninety-third seed dish of the winter last night. These all represent species that prefer, require, or at least tolerate cold stratification. The warm germinators, 75 or so additional species, will get started in late February. My intent is to have most things germinating by 1 March so I can move them to a cold (and still occasionally freezing) greenhouse. But there are always surprises (or my unwillingness to accept their germination patterns despite repeated observation). Lewisia rediviva, Erysimum asperum, and Leptodactylon watsonii, for example, always seem to begin germinating during cold stratification, usually early January after an early December start, and I have to figure out what to do with the germinants before they rot. Starting these outdoors would be a lot easier, but I would miss the entertainment of expending large amounts of energy on configuring some contraption involving artificial lights and a propagation box to keep them growing during the depths of winter.

And it's not like I have room for 250+ species--that may be why so many are no longer here...

Off to a roaring start this year.  Last summer included Narcissus asturiensis collected from a friend's house.  That is already showing a few grassy leaves emerging from the seedling pot.  The Cyclamen are succulent and the Erythronium have swollen from a 24 hour soak.  I hope to at LEAST see leaves this year. 

Cold chill needed for the Campanulas, Silphium, Liatris, and Prunus.  (Anyone growing P. prostrata?  In the Seed Ex this year, it looked curious, if not lovely for the rock garden.)

The Lilium superbum are in vermiculite at 20C until I see a bit of something happening.  Oy... and then for the 5 or 6 years until flowering.  Rick, I think that scaling is the way to go!

The darn red squirrel came into the house (!) and ate all the Platycodon from last year.  I guess ate is not quite accurate - rather, made to disappear, as I don't know what he did with them afterward.  There was NOTHING!  Including the nothing of the 8 Chamaecyparis obtusa 'Nana' (the really nice, true one) grown from cutting last winter.  Vanished... into thin air, like he carefully removed them from their quarters, tossed them into his backpack, and off he went.  So much for my protected cold room...

Many more seeds to go.

I grow Prunus prostrata (or at least what was sold as Prunus aff. prostrata) though not particularly well.  It's been in a trough since I got it in 2008 where it has been very slow growing. If I get up the nerve, I may try to move it to a tufa bed and see if it will take on a prostrate form.

Déjà vu is just the French phrase for the feeling that something has been seen before.  :)

A few seedlings:
Gastrolychnis apetala (syn. Silene uralensis ssp. apetala); germination started in 2 days after sowing at room temp, several seedlings after 4 days):

Campanula topaliana; germination started the day after sowing  :o, lots of seedlings after 4 days:

Salvia pachyphylla; germination in 7 days at room temp, though only 2 seedlings:

Arenaria pseudoacantholimon (germinated in 6 days from sowing, room temp conditions):

I'm sure we have all, from time to time, puzzled over the identity of a mystery seedling!  I think it would be useful to post some photos of seedlings as they progress to more-recognizable stages... a modest start towards building up a bit of a reference database, and carrying on from some efforts in last year's seed season.  Any thoughts on this?

That sounds like a great idea!
Until that, or something like it comes about, here are some new ones and some updates on others:

There is a definite familial similarity between seedlings of the locally native Saussurea nuda var. densa and Saussurea nupuripoensis... (both of these have been easy to germinate... if there is a challenge, it will be in growing them!)

Here is Saussurea nuda var. densa; the seeds germinated in 9 days in room temperature conditions:

Here is Saussurea nupuripoensis which germinated in 5-6 days at room temperature; the seeds were from Vojtech Holubec, and collected in Zhdanko, Sakhalin, Russia at 400m elevation from a scree habitat  (description:  "caespitose plant, 20cm high, lanceolate tomentose leaves, lilac flowers in terminal cymes, 2011 seed").

Arenaria pseudoacantholimon; seeds also from Vojtech Holubec, ex. Palandoken, Turkey at 2300m elevation, from limestone scree (description:  "compact cushions like Acantholimon, 5-10cm wide, spiny leaves, 8 mm long, white flowers on thin 10-15 cm stems"; seeds collected in 2011):

Acantholimon saxifragiforme is taking on an acantholimon-like look as the true leaves emerge:

That germination information is very interesting Rick.  I was particularly struck by Table 3 that indicates to me that chilling is required for at least 2 months and maybe 4 or 5 months for high altitude species, based on their experiments with Eriogonum.

I use two strategies for seed starting.  Those that need cold stratification are left outside with a cover to experience alternating temperatures.  Those seeds that need warm temperatures I start in a greenhouse.  If I get seed from the exchange at the end of January the challenge is that, in our climate, I don't have 2 months of suitable cold stratification weather remaining before spring.  I have observed that I get better germination if I sow outside seeds in November so that there is a full winter period for cold stratification. So some seeds that I receive in late January I now save for planting the following November.

I have outside seed trays of Lewisia rediviva and Douglasia nivalis sown last November that germinated in January.

I do that more and more now, too, waiting to plant seeds next season.  Maybe partly because I don't get it all done as early as I should.  It seems to be preferred by a lot of fritillaria people, and certainly could be better for seed that might do better when aged, like penstemon and some cactus.

Yes Trond, they were last years seeds.  Some of the seed exchanges I use don't send seed until April which is too late for strat.  And then I also get excess NARGS seed and they don't arrive until April-May, so I have plenty of seed that sits around until the following fall.

Fermi, I've always been curious about your seed sowing technique where it looks like the gravel mulch is "domed" and filled right to the brim of the pots; is this done for drainage purposes?  From what I've seen, you get good germination.


Submitted by Boland on Fri, 02/10/2012 - 18:56

Like Mark said, I don't recognize half the seeds you are growing Lori....I assume these are mostly Halda or Holubec seed? (In which case, most would not be suitabe for Newfoundland as we are too wet).


Submitted by Boland on Fri, 02/10/2012 - 18:59

BTW, I would have thought many of those genera needed a strat period..yet you didn't.  How do you know which to do and which not to do? (I follow the ORGS site but many of the more unusual seeds are not listed there)


Submitted by Lori S. on Fri, 02/10/2012 - 20:04

Thanks for the info about Syncalathium/Melanoseris, Mark - I'll add that to my records.

The very unfamiliar things I'm growing are mainly from this year's (and past) orders from Mojmir Pavelka and Vojtech Holubec, collected in Turkey, China, Macedonia and Greece, Kazakhstan, and Russia.  (I'll go back into that posting and add some more detail about the species, provenance, etc..)

So far as deciding whether they'd need stratification or not, well, I make some wild guesses!  
I made the assumption that Brassicaceae and Asteraceae may be less inclined to need stratification than some others.   What does everyone think about that?
If they don't germinate after, say 3-4 weeks, I put them in the cold room for some chilling, and pull them out again in 6 weeks or so for another try.

I scarify all Fabaceae, and then try them at room temp, which usually works.  (I think that's pretty standard... ?)

Other than that, I rely a lot on an article by Alan Bradshaw (Alplains) about seed starting that was published in the CRAGS newsletter, which gives some useful guidelines for which genera generally need stratification and which don't... and I refer to Dr. Deno's texts, although many of the more exotic genera aren't covered there.


Submitted by Hoy on Sat, 02/11/2012 - 01:40

Lori, Syncalathium souliei looks very exiting! Hope you manage to grow it.

Firstly I set my seedpots in a temperate room and then bring them to a colder place if they don't sprout in  two - three weeks. Some montane species like Cremanthodium sprouts immediately in 10-15C other prefere higher temperature.


Submitted by Boland on Sat, 02/11/2012 - 16:36

I agree that Syncalathium souliei looks like a keeper!

Lori, are you growing Inula rhizocephala?  I have seeds from two sources and neither germinated...maybe THEY need stratification?


Submitted by Lori S. on Sat, 02/11/2012 - 16:58

Looking back at my notes, I grew Inula rhizocephala in 2009 at room temperature and had germination... enough to result in several plants to set out.  I didn't note how long it took to germinate.  So, perhaps it might have done better with stratification, I don't know.


Submitted by cohan on Sat, 02/11/2012 - 23:24

Good show Lori and Fermi :)
I looked at the Syncalathium when looking over Holubec's offerings- I'm more and more enamored of many Asteraceae, but some of these Himalayan oddities are especially exciting...

Hi Mark,
not sure if I picked this up from the Brits or someone here ;D - in UK literature it is referred to having the topping "proud" of the rim! Watering has to be from below or by a very, very gentle trickle. The potting mix is not tamped down so that the mix remains well-aerated, it gradually settles down over time.
The idea is that the seedling emerges above the rim of the pot because when the soil level settles down below the rim then it leaves a hollow which doesn't allow good air-flow and this can lead to 'damping off' of the seedlings. At least that's what I've heard and the sinking of the soil level is a problem if the seedlings aren't divided quickly.
I hope this makes sense :-\

I can only just about keep up! There is some great information in this thread. I have quite a few of the seeds Lori mentions from the Czech collectors yet to sow. Really interested by the Ebenus species; I grew E. cretica from Archibald seed for several years in the garden - lovely foliage and rather extraordinary heads of flowers, all in all like a cross between a clover and a lupin. I have seed of quite a few Dalea species from Alplains, and find these legumes completely fascinating (for one thing there is no end of them!). Now the days are getting longer and brighter, conditions are improving for sowing in the greenhouse, so hope to have some things to show in a while.

Thanks, Trond.  I figure the only way I'll get to see some of these things is by trying to grow them!

I've had to resow Thymus aff. haussknechtii after a set-back.  The seedlings died off after I removed the pot from the covered tray.  I think the roots had not yet extended down through the fine crushed granite top dressing that I'm using this year, and so did not find enough moisture.  I tipped out the crushed rock and sowed the remainder of the seed in the pot, where the roots will be able to penetrate down into a finer-grained (but still very permeable) mix.

Update -  true leaves on Cancrinia tianshanica:

Onobrychis argyrea - I grew this 2 years ago and was quite surprised that it didn't winter over, so I'm trying it again; the seeds germinated in 6 days after scarification. It did bloom in the first year from seed, which was nice, though the flowers were not so intricately-patterned as on some Onobrychis.

 
Here is sainfoin, Onobrychis viciifolia, an escape from cultivation, that has beautiful flowers:

Silene bolanthoides - germinated in 8 days at room temp; seeds from Pavelka (1700m, Kaz Dag, Turkey; dwarf dense cushions, short linear leaves, flowrs solitary or 2-4, stemless or very short scape, white to pale pink, petals deeply bilobed, 1.5cm across; rare, one of the best of Silene kinds; stoney places, 2008 seeds); a delightful plant - I'm growing more for backup, and possibly to disperse at the CRAGS plant sale.
 

This is supposed to be Leyospora pamirica - a Brassicaceae, from Holubec (China, Kunlun, 4200m, cold alpine scree, small caespitose pl, 3-5cm high, fleshy dark green lanceolate lvs, solitary large rose flws, 15mm wide, thin peduncles, 2011), but I suspect it was either an errant seed or was mislabelled, comparing to the photo. Should be interesting, nonetheless!  It germinated in 4 days at room temp.

Well, that's the first time I have seen a transitional stage that is not somewhere midway between the initial and final stage.  Oh wait, I am forgetting that the first leaf is actually a cotyledon, so it doesn't count.  Still, I don't think I have ever noticed the first true leaves to be so drastically different from the rest.

Yes, always! The easy ones are fun but I always end up with plenty of empty pots at the end of the season, when I lose interest.  (Yeah, I know I should be keeping these over the winter or for even more than one year, but I have limited patience!  I keep some.)  I've started keeping slightly better records in recent years (though I always end up with some gaps!) - I got something like 65% germination on a species basis in 2010, and only 45% in 2011!  I tried lots of South American species in 2011 that I was spectacularly unsuccessful with.

Lori....I'm curious....I notice that some of your seed-pots are covered with sand and some with grit. Is there a reason for this or is it just random?


Submitted by Lori S. on Sat, 02/25/2012 - 12:41

There's definitely randomness there, Amy, but I am using sand or grit as a top-dressing in most pots this year.  I thought it might reduce algae and moss growth on the top of the soil, which might be helpful for things that take a long time to germinate, and I think it is helping with that.  I thought the grit, in particular, would be useful to elevate very tiny seedlings above the soil surface, so that they can't be overgrown by moss and also so that they aren't momentarily inundated when I water the pots.


Submitted by AmyO on Sat, 02/25/2012 - 13:02

OK, that's answers that. I use the grit as a top dressing on all my pots and it seems to help with the moss/algae problem. Any bits of perlite not covered turns green almost immediatly and fools me into thinking something is sprouting! >:(

I'm having a small problem with some seedlings just sprouting then withering and disappearing. It doesn't look like the typical damping-off symptoms, but it could be that as I never sterilize my containers. There is also a pot of Campanula zangezura and a pot of Anemone rupicola that are looking very chlorotic, but they have been fertilized with no change. Other seedlings are looking nice and green growing right alongside them. In addition there is a pot of Aconitum sp. that has developed brown seed leaves....I don't know if that is something to worry about, but hoped someone here might have some advice for me on these problems. :rolleyes:

I was thinking the same thing!!!

My germination results usually hover around the half mark, and last season was a particularly bad year for me, too.  A couple other seed growers in my Chapter also tally in at 50%, in general.  These are first season results.  Seeds that sprout in the following seasons are a bonus. ;D


Submitted by Lori S. on Sat, 02/25/2012 - 19:17

I think your seedlings look terrific, Amy!  I would imagine the ones you feel are a bit chlorotic will probably come around.  I wonder if the browning of the Aconitum seed leaves isn't just the effect of the light source somehow (e.g. very close to the lights, which is probably overall a good thing, nonetheless)?  They look otherwise pretty darn healthy.

Rick, it's great to hear that your stats are in the 50%-ish range too - very encouraging! 


Submitted by Hoy on Sun, 02/26/2012 - 02:09

My results also usually are about 50%. Last year I had a much better result, however, I lost a lot of seedlings in the summer. It is a problem though not being at home long periods in summer.

Amy, my thoughts were the same as Lori's. The reddening of the leaves are almost certain a result of too intense light level - did they sprout there or have you moved the seedlings?
I have found that chlorotic leaves can appear due to too much water and/or too cold temperature. It can also be caused by lack of some important nutrient of course but usually the plants improve when repotted later on.


Submitted by AmyO on Sun, 02/26/2012 - 07:09

Thanks for the reassurances Trond & Lori!  :D
The Aconitum did sprout there under the lights and perhaps they a little too close, so I'll raise a notch or two.
The temp. is in the 60*f - 65*f area for the most part.

My record keeping is really bad to non-existant so I can't chime in on percentages of germination. But if I can remember clearly enough I would guess at 40-50% as well.


Submitted by Lori S. on Sun, 02/26/2012 - 09:36

Myself, I wouldn't bother to take any particular measures concerning the seed leaves - they look healthy, just reddened (maybe it's normal in that species, who knows?)... and they're going to die off later anyway.  So long as the true leaves are alright - and they look fine - I'd keep the light as close to the seedlings as possible.  Light seems to be the most important factor to starting seeds indoors, and if there is a problem, it often comes from inadequate light, as opposed to too-intense light.


Submitted by Hoy on Sun, 02/26/2012 - 10:00

Yes, Lori is right. I wouldn't bother either. Although the light could have been too intense if the seedling had germinated in darkness and suddenly brought too close, the plant soon adapt and will take all the light you can provide with a lightbulb or tube.

Lori, you are not stratifying a bunch of genera that I thought had to be...for example, I strat all my Saussurea, Patrinia and Campanula.  I have to seriously revisit my germination practices.

I have about 45 pots that have not sprouted after 4 weeks in the heat...they were all previously startified for 8 weeks.  Guess I'll stick them outside now to freeze-thaw until April and maybe they'll sprout then (unless the seed are not viable).

My seed from Goteborg's BG and Graz BG just arrived.


Submitted by Lori S. on Sun, 02/26/2012 - 13:01

I usually stratify Campanula... although I've gone the other route occasionally and found the odd species that doesn't seem to need stratification at all, e.g. Campanula topaliana.  With Saussurea, I think it was the absence of much info that caused me to start them in warm conditions, although not always successfully by any means.
I wouldn't be surprised at all if you get much better germination than I do, overall, with the stratification.  In some cases, the one or two seeds that germinate for me in warm conditions may just be the "oddballs" among the population in the seed packet...  At any rate, stratification is certainly not harmful (which seems to be something people often wonder about).

Edit:  I have only got one seedling of Campanula scoparia, which may suggest that stratification would have been the way to go for it!  Time will tell if it really even is Campanula scoparia.

Really wonderful to see all those seeds germinating - and to see someone else with Lactuca intricata! Who but an alpine grower would want to grow a shrubby lettuce. I have this germinating too and really look forward to seeing what it does.

My experiences are that only around 50% of seed generally germinates (although I get much better results with home collected seed). Peter Erskine in one of his articles in the AGS Bulletin quoted a similar figure, so it seems reasonable even when you try every which way to improve germination.

We are having superb warm sunny days here and a lot of seeds are beginning to come up. The amsonias quite surprise me - tomentosa - the seed is very large relative to other species I have grown, and Alplains advice to sow warm has worked well (others I have always sown outside over winter). Eriogonum caespitosum and Saussurea I received late and put in the fridge after sowing for 4-5 weeks; they are coming up nicely now. Similarly Edraianthus pumilio, one of my all time favourites. The Dudleya was very old seed from Ron Ratko, and like Buddleya utahensis, tiny! These have germinated with bottom heat in the greenhouse but are growing on very slowly. Quite a bit more to come (and quite a bit more to sow!).


Submitted by Mark McD on Thu, 03/15/2012 - 18:10

Such fun to see all these seedlings popping up.  Tim, your mention and photo of a "Buddleya utahensis" sent me googling, and some interesting things came up.  First, is the genus spelling, which a wikipedia entry asserts is commonly misspelled Buddleia, but it is actually Buddleja (as you have spelled it on your label). The reference goes on to say "Linnaeus posthumously honoured the Reverend Adam Buddle (1662–1715), a botanist and rector in Essex, England, at the suggestion of Dr William Houston. Houston sent the first species of buddleja known to science (B. americana) to England from the Caribbean about 15 years after Buddle's death".  I wonder how it got the "ja" ending to its name?

Regarding genus classification, it says "The genus Buddleja is now included in the figwort family, Scrophulariaceae; it had earlier been classified in either the Loganiaceae or in a family of its own, the Buddlejaceae."

Checking IPNI.org, there are only entries for Buddleja, none for Buddleya or Buddleia.  Checking The Plant List, both Buddleja and Buddleia are listed ???, stating that the Genus Buddleja is in the family Scrophulariaceae, and that the Genus Buddleia is in the family Loganiaceae, yet these are supposed to be one and the same!  What a muddle of a buddle ;D

I never gave it a thought that there are western American "Butterfly Bushes" or Buddleja species, now I'm enlightened. :)

Regarding Buddleja utahensis, here's a link showing what it looks like, a subtle dryland shrub; the flowering stems are floccose with tiny yellow flowers peaking out, intriguing.  On the link below, check out Buddleja marrubifolia, that one looks very ornamental with bright orange-red flowers and as expected, nice Marrubium-like foliage.

Mark - I'm not sure where I got the 'y' from, especially since I labelled the plant with a 'j'. I must have been halfway further on in the sentence! Very interesting to hear more of the background of the genus and family(s). I have always liked the genus, quite apart from its attraction to butterflies and other pollinators, and we have grown a number of more unusual species over the years, including crispa, a lovely thing that I first saw at Beth Chatto's, and colvilei, which has relatively enormous flowers. I hadn't come across some of these American species before, and there are several more in South America pictured on the Chileflora site. There is a book on the genus, published by Timber Press, which I have been meaning to get for some time so will have to check it out again.


Submitted by Mark McD on Fri, 03/16/2012 - 06:01

Tim, maybe because in your sentence about Buddleja you first mention the genus Dudleya, practically a rhyming anagram for Buddleya/Buddleia/Buddleja ;)  But the revelation for me, when researching the name, is that it really is Buddleja, while all these years I used the common misspelling of Buddleia, but then again, The Plant List seems equally confused, not sure how such an authoritative resource can be sitting on the fence and presenting both Buddleia and Buddleja as valid, it is one or the other as far as I'm aware.  Regardless, all interesting stuff.  :D

Everything is looking great, Tim!  
What does your Lactuca intricata look like?  Here's mine, looking very lettuce-like indeed at this stage.  It's transformation into a subshrub should be interesting.

http://www.pavelkaalpines.cz/Photos/Turkey2009/lactucaintricataturkey.html

Aethionema saxatilis ssp. oreophila - seeds from Pavelka (collected:  2300m, Aroania Mts., Greece; small glaucous plant, 3-6cm, pale pink flws, limestone rocks); seeds germinated in 11 days at room temp.

Anthemis cretica ssp. leucanthemoides - seeds from Pavelka (collected: 1700m, Kaz Dag, Turkey; very dwarf plant woody at base, linear silvery-green lvs, solitary white flws, 3-8cm, stoney places, 2008 seed); germinated in 6 days at room temp.

Bukiniczia cabulica - germinated in 10 days at room temp.  I got seed from both the NARGS and SRGC seedexes and put both in the same pot; the SRGC seed looked like Acantholimon (and has not germinated yet - perhaps not fertile) while the NARGS seed appears to be the real McCoy; either way it seemed I would get something very interesting!

Hi Lori - yes that really does look lettuce-like! My seedlings are still very small. We have grown for many years a big herbaceous 'lettuce', Cicerbita plumieri (also sometimes labelled Lactuca). This is a very robust plant to 2.5m or more, with the typical violet-blue flowerheads. I've always liked it so I look forward to seeing what this species does. In the past I also grew Cichorium spinosum, and this is very attractive and neat, and would be nice to get again.

A pretty meagre salad though... those are only 2 5/8" pots.   :D

A few more including a couple that have been potted on:
Linum viscosum - seeds from Alplains; started germinating in the cold, after 1 month in the cold room:

Draba tomentosa - seeds from Pavelka (collected: 2500m Korab Mts, Macedonia; dense grey cushions, big wh flws on scapes 3-8cm, limestone rocks); germinated after ~20 days at room temp.

Androsace bisulca v. brahmaputrae - seeds from Holubec (collected: China, Gyamda, Tibet, 3700m, mountain grassland, unique plant, rounded cushions, 3-8cm wide, 1-2cm rosettes, large rose-red flws on 2-4cm long stems, 2010.  Also China Zhoka, Tibet, 3500m, rock terraces, 2010); started germinating in the cold, after 33 days in the cold room:

Anarthrophyllum desideratum - seeds from Holubec (collected:  Argentina, Col. Belgrano near Perito Moreno); scarified then germinated in 10 days at room temp;  so far, so good, though only one measly seedling... poor thing probably won't stand a chance in the real world outdoors!


Submitted by Tim Ingram on Mon, 03/19/2012 - 05:19

Oh what dreams are made of if you could grow the Anarthrophyllum! I did try this once from John Watson's seed, but like a lot of South Americans the seedlings became very drawn and out of character (I think you need to put a UV lamp over it!). I am really attracted, like Anne Spiegel, by dwarf legumes, and the adesmias are another group that would be exciting to grow. There are also some excellent South American lupins and one we grew back in the 1990's was L. oreophilus, which I have seen again recently on the Chile Flora site. This grew well in the garden but like most lupins (well all) was relatively short lived. Unfortunately I only have slides from the dark ages of film!

I once germinated Anarthrophyllum desideratum, a single seedling that lasted about 1 month, huzzah.  Lori, I hope you have better success than I, one of the more amazing plants on this earth.


Submitted by RickR on Thu, 03/22/2012 - 04:35

Globularia trichosantha - uniformly germinated in 9 days at room temperature.  This was my third try with this species, each from a different source.  The first two times (other years) they were winter sowed without any success.  They might have been bad seed, I suppose, but more likely rotted over the winter.  These first two batches were seed lightly pressed into the soil surface, then covered with #2 granite grit.  In the third try with the same soil mix, seed was sown on a bed of #1 granite grit, and covered with the #2 grit, and put directly into 68-70F temperature (not winter sown).
             

I received Eranthis hymenalis seed from Wim last year.  He sent me some in moist packing and some dry seed in May, so the dry seed couldn't have dried that long, I would think.  They were promptly planted 11 May 2011 in pots and left outside.  With the crazily warm temps here (a week of 70-79F days and 55-60F nights) both lots came up simultaneously 16 March 2012.  
             

Oxytropis nana - germinated at room temperature in 2 days after scarification and 2 hour soak.  It was quite amazing how quickly they absorbed water.  In the 2 hours it seemed like they doubled in size, but in reality they increased in size by about 50%.

I did a second trial at room temperature with an equal number of seed from the same batch (NARGS Seed Ex seed wild collected in Wyoming) unscarified and not soaked.  One seed emerged in 35 days, so far.
             

I am a bit puzzled by this one: it's supposed to be Oxytropis campestris.  Scarified, and germinated in 7 days at room temperature.  It looks like a monocot to me.  Oxytropis is a dicot.  Any ideas?
             


Submitted by Hoy on Thu, 03/22/2012 - 05:41

Rick, it is a dicot and a Fabaceae. The pea (cotyledons) often remains in the soil. But I can't tell if it is an Oxytropis ;)


Submitted by Mark McD on Sun, 03/25/2012 - 08:59

Rick, I agree with Trond, it does look like a Fabaceae to me, almost Lathyrus-like, but some Oxytropes and Astragali have upright growth, such as O. campestris, so it might be right.  Here's a photo, its a lovely locoweed.
http://www.em.ca/garden/native/nat_oxytropis_campestris.html

We too have had a full week of record breaking warm weather 75 F - 83 F resulting in a sudden explosion of rapid plant growth and flowering, full bore flowering of Magnolias, cherries, daffodils, everything!  Seed flats that I leave out all winter are bursting with germination, flats of Jeffersonia dubia and diphylla coming up so thick that the soil and mulch top dressing lifts up like a lid.  First time ever getting good germination on Anemonopsis, very happy about that.  Epimedium seed coming up thickly too, both those that I've sown, and innumerable self-sown ones out in the garden.

But as expected with such mild winter weather overall, followed by a heat wave of sorts, cold is returning with a deep freeze predicted for tomorrow night, 19 F (-7 C), followed by several more nights of hard freezing.  I'm not sure how the seedlings will withstand a sudden drop to 19 F, so I'm not taking chances with my flats and brought them indoors for a few days until temperatures moderate, I don't want to risk the bonanza of Anemonopsis, Jeffersonia, and Epimedium seedlings.

Well, nothing but fast-draining soil, really.  I've only given them a bit of fertilizer in the water once recently for the first time.  
We'll be getting ready to put them on the cart to start spending their days outdoors soon (wheeled into the garage at night)... I'm out of room inside here now, so planting more seedlings into individual pots will depend on creating more room this way!

I shouldn't keep so many seedlings of each kind I guess, but I hate to kill them, despite that I know I'll end up giving lots away (or perhaps I should admit to forcing them on people  ;) ) just to get rid of them... wish I could send you all some!  I do try to flog them at the local rock garden society spring plant sale, but it seems that most people are extremely unlikely to even consider trying an unfamiliar species.  (I'm the opposite, evidently!)

What a perfect description!  I would imagine that the good lighting helps a lot, too.  The flowering anaphalis is wonderful surprise!  Lori, how many hours a day are your lights on?

Every year in our Chapter newsletter, I always write in my plant sales article: "We encourage all contributors to clearly print plant names (botanical and common) and cultural information on the label.  Putting your own name on the tag is an added bonus.  We all like to know who grew our newly purchased plants (and who we might ask for additional plant information)."  Although I always have people asking me for more information about my donate plants, few actual take my advice of put their own names on their own donated plants.  I am at a loss of how to get people to do this.  Any ideas?

Another thing that works very well to sell unfamiliar plants, is write an article about them in a prior Chapter newsletter.  I think the best one I ever wrote was on Phyteuma (with pics, of course).  I still have people asking me, years later, if I will be bringing any.  The good thing is that someone is now also growing them from seed, and donating to the sale.  But she won't put her name on them!

Yes, that certainly is a fine turn of phrase!  ;D  Rick, the lights are on for 16 1/2 hours per day, set on a timer.  There are 2 or 3 4-foot long fluorescent shop lights suspended on chains over each shelf; each shop light contains 2 bulbs of 40 watts each.

Thank you, Amy.  The seeds are really doing it all themselves - I've just been providing the grunt work of planting, watering, and potting on.  I've been mostly showing the easy ones, needless to say - I will bomb out totally with many species that are not inclined to germinate so readily, or that may need different conditions than what I can offer (e.g. cool growing conditions, perhaps?)

Rick, how about publishing a list in the local club report of who sold what, for later reference?
The president of the local rock gardening club has proposed that members who flog plants at the spring sale prepare slide shows for the upcoming May meeting, to show people what the plant will look like, and to talk about their experience at growing it.  I will be doing this, for some of the species I grew a couple of years ago, that I am now growing more of with the hopes of dispersing at the sale.  (Of course, that doesn't help with the totally unfamiliar things I'm growing and have no prior experience with... and yet hope to disperse!   Actually, I often wonder why I am doing any of this... just want to get rid of excess plants, I guess.)

I grew Corydalis wilsonii from seed in 2010, was planning on a warm/cold/warm treatment, and they came up in the first warm conditioning.  Plants don't survive zone 4 winters, but apparently the seed does better.  Just a couple days ago I spied a seedling emerging from warm/cold/warm (summer/winter in garage/spring).  The pot probably only reached a 10F(-12C) low.  Also, remember our zone 4 spring is a month ahead this year.

Rick,
at our AGS Vic Group we have an annual plant swap known as "The Bunfight" because the original ones used to be a bit of a shemozzle. We ask for donors to put their initials on the back of the label so that we can identify the plants that way. It's less time consuming than writing their whole name and we now get quite a high compliance. I always like to acknowledge people from whom I've received something which has gone on to be a star in the garden.

Cohan, I usually end up with a bunch of these too, I'm always disgusted with myself that this happens but it does! Anyway, I normally end up putting them outside, and if it's something I really want badly, I may try a few seeds indoors in the warm as well.
I don't have a dedicated fridge I can use either, just a few spots way in the back of always in use fridge for maybe 3 - 4 small pots that I have to watch like a hawk that no one tips them over! So, outside they go.

Lori, I keep wondering where you are going to put all those new treasures ;)  Seeing all of these plants at the early germination stage, with first leaves, is most educational, a resource unto itself.

Not knowing much about Anemonopsis macrophylla, I've been frustrated by the fact I never get any seedlings in the garden, even when I help things along by scratching in the seed out in the garden around the mother plant, which has proved so effective for many other plants I do this with.  Last summer when the seed was ready, I harvested some of it and sowed the seed in a flat, top dressed with decomposed pink bark mulch, keep in shade and just moist for summer and fall, and left outside all winter, and I'm so pleased to finally have a fine crop of seedlings coming up.  Now, only 4-5 years until full sized :o

Googling this plant, I'm surprised by the wikipedia link that says "As with many other members of the Ranunculaceae, seedlings of Anemonopsis form only cotyledons in their first season; the first true leaves form the year after germination".  I wasn't aware of that.  Can anyone comment, is it true that's all I'll get this year is pairs of cotyledons and no true leaves?

Two years ago I received a lots of fresh Trillium seed in mid-late summer, over 20 different varieties.  I expanded some of my beds outdoors with the purpose of sowing all the seed outside directly in the garden.  I was hoping, since the seed was fresh, that I could get accelerated seed germination the first year (hypogeal germination, followed by true cotyledon germination) all in one season, which can happen.  The following spring I got only a few seedlings, out of an estimated 2000-2500 seeds sown. 

This year is the 2nd spring for the sown trillium seed, thankfully many are now showing good germination.  The following photo (sorry, not very good quality) shows a view where I marked the location for seed sown of Trillium pusillum v. alabamicum.  There is one bigger leaf, it appeared the first spring.  But looking closely, there are about 20 fresh seedlings appearing.  Will probably need to wait another 4-5 years before flowering.

Now, only 4-5 years until full sized :o

Googling this plant, I'm surprised by the wikipedia link that says "As with many other members of the Ranunculaceae, seedlings of Anemonopsis form only cotyledons in their first season; the first true leaves form the year after germination".  I wasn't aware of that.  Can anyone comment, is it true that's all I'll get this year is pairs of cotyledons and no true leaves?

Mark...I sowed seed from my plants 2 years ago, and I can say for sure that now in this second year is when I am seeing true leaves on them. Now if the red squirrels & chipmunck would leave the pots alone I'll be all set with many plants in a few years time!

Thanks Amy, then 2 years it is to see true leaves on Anemonopsis, they sure are slow!

May I recommend buying some "hardware cloth", typically available in hardware stores, sold by the foot or yard on rolls, as much as wanted.  Then with standard wire snips (also at the hardware store), I cut pieces of the wire mesh to cover my pots, turned down at the sides to hold the mesh in place.  When seeds germinate, the mesh can be easily bent to give some height to the covering to give seedlings some room and not have leaves pop up through the mesh and expand the leaves, making for a tricky situation removing the mesh eventually and no ripping the leaves off. It works well, even if the mesh is formed into a loose arch over the pots, so far squirrels and chipmunks leave such protected pots alone.

I no longer get great angst over incessant diggings of these varmints in my pots since I started using wire protection.  The wire covers can of course be re-used over and over.

Mark, do you have a picture of your "hardware cloth"? Don't know whether something like that exists here.

A few more things germinating - here Eriogonum ovalifolium, Lomatium californicum and three Asclepias, hallii, latifolia and asperula (from Alplains), which I am particularly excited by if I can grow them on to flowering. These were all sown and kept in the fridge for 6 weeks before bringing out into the greenhouse. All this propagating is beginning to bear fruit as we fill the greenhouses with young plants on the nursery. And finally a lovely surprise in the garden, a mass of Trillium rivale seedlings next to the parent plants. For many years I only had one clone and never got seed set, but have planted several plants from different sources together. However, I didn't expect such largesse!

Have you considered using chickenwire in the same way, Amy?  It costs less than hardware cloth.

Here are a couple views of peat flats protected with small rectangles of "hardware cloth" or "welded wire fabric" or "welded wire mesh", all terms for basically the same thing.  In the photo on the right, the mesh has been loosened to allow room for the developing Jeffersonia seedlings.

They look pretty tough, Mark, not like the chicken wire I use! But my main problem is not warmblooded animals either. . . .  However I could need it where I plant some of my bulbs. They are often dug up and eaten by some animal.

More babies:
Gentiana tibetica - from Gardens North; germinated in 3 weeks at room temp, as per Kristl's directions:

Potentilla uniflora(?) - locally wild-collected; germ in the cold after ~1 month of stratifying; this is one of the magnificent alpine potentillas that I've struggled to ID conclusively - with a couple of these "in captivity", I hope to be able to finally satisfy myself on the ID!

Erysimum leptophyllum - update; seeds from Pavelka (collected:  1900m, Dedegol Dag, Turkey; dense tufts, linear silky lvs, yellow flws, 3-5cm, alpine meadows; 2010 seed); germ at room temp in 12 days.

Dryas drummondii - locally wild-collected; germ in 4 days at room temp.

Alyssum sp. - seed from Pavelka (collected:  1500m Tahtali Dag, Turkey; very dwarf silver cushions, suffruticose at base, yellow flws 1-3cm, limestone rocky hills, 2010 seed); germ at room temp in 7 days.

Acantholimon caryophyllaceum ssp. caryophyllaceum - NARGS seedex; germ in 5 days at room temp.

Primula denticulata - I used to have a lot of these but no more!; Gardens North; germ at room temp in 15 days.

Astragalus loanus - NARGS seedex; as described in Stephanie Ferguson's article in RGQ Vol. 69 No. 4; germ in 9 days at room temp after scarifying.
 

Achillea umbellata - seeds from Pavelka (collected: 2100m Aroania Mts. Greece; strongly silvery-wh tomentose cushions, white flws on scapes 5-15cm, limestone rocks); room temp

Looking back through my photos, the ones I've grown have shown some variability in that regard.  P. albidus, virgatus ssp. asa-gray, and pumilus have the narrowest cotyledons among the ones I have seedling photos of, while P. euglaucus, attenuatus, brandegei, grandiflorus have rounded cotyledons.  P. venustus is sort of intermediate.  With such a large genus (about 270 species), I suppose there's bound to be variation!   :)

Day 2 of hardening-off for 9 trays (~400 pots) of seedlings:

I used to put the trays out in the shade for 5 days for hardening-off, but we are instead using shade cloth on the plant stand this year.  The shade cloth excludes 60% of the light, and seems to be doing its job.  The stand can be rolled into the garage if frost is forecast.

I like that reference to Gerald Durrell - I was hooked on his books too (I have 12 in addition to 'My Family and Other Animals'!). Not so easy to write about plants like this. I am keen to try more legumes in the garden (and to grow for the nursery) so have just spent several days chipping seed of oxytropis, astragalus, dalea, sophora and lupins. Some seed (especially the first three) are minute so this magnifying light that my wife uses for embroidery has come in really useful. Now I need to germinate and grow them on...


Submitted by Hoy on Wed, 04/25/2012 - 11:20

Tim, I use sandpaper with different grit size when I "chip" peas. I have one lying at the table and one mounted on a piece of wood. Then it is very easy to chip all at once and I always get very good germination.
However, I'm not sure whether they are easier to grow on . . . .  ;)


Submitted by RickR on Wed, 04/25/2012 - 16:33

I am in no way an expert at this, but I use sandpaper to scarify seeds, too.  Except I don't use sandpaper with a block of wood.  Seeds are rolled between sandpaper on the table and a piece above with bit of downward pressure from my fingers only.  Logically, one would think that with a block the larger seeds would be be scarified while small seeds in the same batch would not; the small seeds would be protected from abrasion by the larger seeds that would prevent significant sandpaper contact. ???  Or perhaps the larger seed would be scarified too much?

I've thought a magnifying light like that would be very useful for sorting/cleaning seeds!

I was very pleased to notice that seeds of Sorbus sp cf wilsoniana sown last spring are now coming up abundantly!
I don't know much about what this will look like, especially being 'cf', but here's a description of the species:

http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200011724

interesting that they say fruit orangish red, when many pics you can find online show pink berries (darn, I'd rather have had pink! maybe the cf will take care of that...).. and 5-10 m-- 5 would be preferred, but I'll have to wrap it in something to keep the moose from eating it- it took decades for our regular Sorbus ( I never remember which it is- americana or acuparia? the one with hairy buds, I think) to become more than a multi-stemmed shrub, what with annual pruning by them- it finally shot some trunks higher, and now they eat around lower levels...

I also have S reducta seedlings from last year planted out already and showing slight signs of life... that one might stay low enough to be below snow when the worst predations occur...

Rick, I always scarify only one species at the time and the seeds tend to be rather similar in size. When I use the block the larger seeds tend to roll a little and the they get separated from the smaller and I can tilt the block if necessary. Anyway it works fine!

I scarified seeds awhile back, I managed to scarify my fingertips as well!  I managed to hold most of the needs with a finger, and used an emery board.  For the smaller ones I put them in a baggie and "cornered the seeds" and then went at them with the emery.  Seemed to work, most have germinated.  I need to find a better way....

All photos taken 9 May 2012.
All were winter sowed the first few days of February:

Alyssum stribrnyiRomneya coulteri and Alyssum oxycarpum germinated in a warm spell of mid March.
       

Iris were soaked for one day before winter sowing.  Iris (setosa interior x hookeri ‘Labraska’) x self emerged 8 April.
             
Other Iris seed sprouting dates so far:
Iris hookeri x ensata F3 – 4 April
Iris setosa nana – 25 April
Iris tectorum ex ‘Burma Form’ – 25 April

Moltkia petraea  germinated 4 April, and Mysotis decumbens 20 March.
       

Petrocoptis pyrenaica emerged 20 March.
   

Phemeranthus sediformis emerged 31 March and Physaria alpina 19 March.
       

Pulsatilla halleri ssp. rhodopaea emerged 30 April.
             
Other pulsatilla emergence dates:
Pulsatilla halleri – 25 April
Pulsatilla grandis ‘Budapest’ – 28 April

All these were sowed at room temperature:

Acantholimon kotchyi, germinated in 8 days.
             
Other acantholimon emergence dates:
A. caryophyllaceum – 7 days
A. venustum – 7 days
It was interesting the these species first emerged as brown seedlings, and only turned green later.

Delosperma ashtonii germinated in 9 days.  But subsequent placement outside has yielded very little growth.  Delosperma are usually very fast growers, at least in warm weather…
             

Dianthus haematocalyx ssp. pindicola emerged in 5 days, and Dierama pendulum 22 days.  It's easy to see which dianthus seedlings emerged inside the house (with etiolated stems), and which emerged a little later after being place outhside.
       

Globularia trichosantha germinated in 15 days.  I've tried winter sowing G. trichosantha twice before with no luck.
             

Townsendia hookeri emerged in 11 days.
             
Other townsendia emergence dates:
Townsendia rothrockii – 7 days.
Townsendia scapigera – 7 days.

Lewisia rediviva began germinating (April 18) in the refrigerator at 34-38F(1-3C) in 49 days.  I wish I would have taken photos when they first emerged because cotyledons were not elongated at all; they were perhaps only twice as long as wide.
             

Phacelia campanularia also germinated in the refrigerator in 35 days.

Not a new seedling, this one is in its second season.  But I thought the difference in the earlier, simple leaves versus the newer compound leaf was interesting with this Aralia cachemirica.

Germination over the last couple of weeks of some seeds sown around the beginning of May (I think- some of the tags were made earlier and then I didn't get the sowing done, didn't change them all!) and put out in the last patch of snow which soon became a bin of cold water! but still many cool days and near/frosty nights-- Some Violas (have to go out with a notepad to get the names...lol)- several Hieracium (I doubt they really needed the cool period, though the references I found were mixed, so I figured what the heck!) villosum, intybaceum and most recently aurantiacum (hope none of these will be weeds!) and the similar Hypochoeris maculatum; Prenanthes (purpurea, I think-have to look at the tag or find the packet..lol), And some things sown end of May and set outside for (occasionally!) warm days, though nights are still (always!) cool--Sempervivum arachnoideum, Polemonium boreale, probably some other things I'm forgetting now-- I have pics of most, but they don't look like much yet!

I used to use Deno's method a lot - moistened paper towel inside of baggie - but have just gone to direct sowing in pots in the last few years.  It certainly saves space (Deno's method, that is).  It can be a little tricky to detach roots from the paper towel, so I'd just tear away as much as possible and plant it with the seedling.  I was not using it for peonies and roses though.

Mark, I would be tempted to wait for a not-too-hot day, then transplant them soon, separate out the seedlings into smaller clumps of 2-3 seedling each, then mulch and keep them well watered.  I don't have direct experience with Hepatica seedlings, but with other spring ephemerals, I separate and move the seedlings in early to mid summer, with good results.

Looking good, Dave! I have some smaller than that (first year) and some maybe about the same size/age.. I sowed them in an old hanging basket planter (not hung though!) expecting to leave them several years till ready to go in the ground.. they are looking good- finally like real, though small, plants, this year.. Maybe I will plant them out this summer/fall, not sure yet... I rarely do anything with seedlings between sowing and planting out...

That being said i think I'll be potting on/ planting out a few Hepaticas soon as well. :)

Cheers Dave.

Nice Dave! But don't you think they need to be separated soon?

Yip Trond --i'll let them flower first --see if there is any variation within a pot --repot any 'nice ones' and plant out a small number if i can find some room  ;D and probably give away the rest.

Cheers Dave.

Understandable with liverworts ;) When I grow rhododendrons from seed I have to give away a lot of thembefore I have seen the flowers :-\ Have to judge on foliage!

A nice bunch and very reminding of spring!

It is two flowers that I associate with spring. The first I usually found in spring as a child was hestehov (coltsfoot Tussilago farfara) and the second which heralded the real spring was blåveis (liverwort Hepatica nobilis). I had some favorite places I visited regularly :)

Having chipped a lot of legume seed earlier in the spring I decided I should get on and sow it. Summer temperatures are perfect, around 25-30°C and the seed germinated in a couple of days. So far so good. And then an influx of slugs out of nowhere discovered them, causing much cursing and a quick transfer to the greenhouse and scattering of slug pellets. Fortunately some are growing away OK and more have germinated, so at least most pots will produce a modicum of seedlings. Next year I will take more care.

The first photo shows Sophora arizonica with probably half of the seedlings chomped below the cotyledons. The second group were less effected: Lupinus excubitis, Sophora stenophylla and Robinia neomexicana. The third shows Oxytropis prenja, Ebenus pisidica and Hedysarum pestalozzae. Many of these are not likely to be too easy to grow even without slugs around but they are such fascinating plants, and like the final picture of Lupinus chamissonis often have very beautiful foliage even in the absence of any flowers.

I know that feeling perfectly well! Unfortunately I have no slugfree place at all except inside the house :-\

My allotment of seeds from NZAGS arrived a week and a half ago.  I immediately planted a few indoors at room temp. covered with clear plastic and they germinated within a week - leading the pack is Townsendia hookeri, Gentiana verna, Ranunculus lyallii and Pterocephalus perennis.  Also coming along is some of Gene Miro's Ourissia coccinia.  In the past, when I have planted these in early spring, when most of my seeds come in, there is a problem with damp off and some just don't germinate at all.  Hope springs eternal.  Fran

Good luck with all of those Fran :)

I collected a few berries of Arctous rubra, which is now one of my very favourite sub-shrubs, so I'd really like to get some going! Does anyone have any successful germination tips? Sounds like it could be a bit tough.. I will put them out over winter.. right now I have them in a bit of water with a touch of vinegar and kefir, in a highly unscientific effort to give them some simulation of passing through a digestive tract! then, barring any specific advice,  I'll sow them on top of gravel...


Submitted by Howey on Tue, 09/04/2012 - 13:08

Cohan - never heard of Arctous rubra but, after looking at Google shots of it, I'm impressed - sort of related to Arctostaphylus, n'est pas?  Your handling of its propagation is rather heroic, in the medical sense, I'm thinking.  Hope you will keep us informed about your progress with this most interesting plant.  Fran

Fran- yes, close to Arctostaphylos, in fact I think some authors may still retain it under Arctostaphylos.
I'll be sharing some recent photos of it when I get them all sorted, and I think I need to put together a set of it in several seasons- I've now seen it in early spring just emerging and flowering, in mid-summer in its full velvety greenness (I actually thought it was a low Salix until I saw it in flower!) and  beginning fall colour on my recent visit..
I have seen some photos where it did not look so different from common Arctostaphylos uva-ursi, but the plants I am most familiar with, near the foot of Athabasca Glacier, look very different from it- with larger leaves, and many stems coming from rhizomes rather than above ground persistent stems (apparently they do both). It is also variously described as deciduous or 'marcescent' which apparently in this case means the leaves seasonally die but do not necessarily fall off- the plants I've seen mostly seem to shed them, as I only saw fresh leaves in spring.. I wonder if this relates to winter weather- how much snow/wind/rain there is to strip them off? If I do get any seedlings it will be interesting to compare habit here to the alpine location..

I'll never really know if my heroic intervention  will help --well, if there is no germination, I'll know it didn't help! but if there is germination, I wont know if its just due to outdoor winter stratification..lol.. I don't really have enough of the small seeds to try many different things, so there is no control group!


Submitted by Hoy on Wed, 09/05/2012 - 08:44

Cohan, your description could be of the species growing here, A. alpina. Do you know it? What are the main differences, do you know?

I've gotten germination of some Ourisis coccinea from Gene too ;D (Thanks, Gene)


Submitted by cohan on Wed, 09/05/2012 - 17:19

There may be some other differences (I've read the descriptions but forget), but the obvious one is black berries on alpina vs red berries on rubra.
We only have rubra in Alberta, I think- oddly, Flora of Alberta only mentions rubra, but efloras North America mentions alpina as occurring in Alberta, though rubra is sometimes labelled as a subspecies of alpina or of Arctostaphylos alpinus..
I went to check the efloras genus description to see the difference in the species, but the page is down for maintenance..

Dave, what a range of flower colour! 

Tim, legume seedings must be among the cutest... Lupinus chamissonis is a beauty - I must look that one up.

Well done, Fran.  I seem to recall having lousy luck with Pterocephalus... must try again.

Silene petersonii.
Finally some colour today in a pot of seedlings sown ,(x Ron Ratko's seedlist), way back in March 2009.

Having been potted on only once ,maybe well over two years ago, probably accounts for the foliage ,including flowering stem,only being 5 cm in height.

I love how the macro shot shows the prominent veining on the fringed petals of this little beauty.

Cheers Dave.

Cute little plant, Dave.  I wouldn't be surprised if the striping on the calyx remains prominent on the seed pods, as with Silene uralensis (below) and many other Silene:

It would be interesting to see another photo later on when it's in seed.


Submitted by Mark McD on Mon, 10/22/2012 - 15:48

Dave - congratulations on flowering Silene petersonii, it's one that I have always wanted to grow.

Found an excellent image of Silene petersonii, the plants growing among a jumble or rock, alongside the North Loop trail on the NW slope of Charleston Peak, Spring Mountains, southern Nevada (elev. about 3500 m).
On this wikipedia page, there are a number of images sizes, select a large image to see the details.

I think I'll have to try that neat little Silene! And wouldn't you know we sell them at Rocky Dale Gardens! It has nevered flowered in the pot and looked a bit on the weak side so I didn't take much interest. The plants came from Sunny Border and they use a pretty heavy mix. A repotting with a much lighter soil mix might be in order for these to do their best.


Submitted by Toole on Mon, 12/03/2012 - 00:11

Thanks all regarding the Silene --it never set seed ........ :'(

Here's an Ixiolirion tataricum flowering from my own 'home' seed . :P :P

              Oxytropis nana - germinated at room temperature in 2 days after scarification and 2 hour soak.  It was quite amazing how quickly they absorbed water.  In the 2 hours it seemed like they doubled in size, but in reality they increased in size by about 50%.

I did a second trial at room temperature with an equal number of seed from the same batch (NARGS Seed Ex seed wild collected in Wyoming) unscarified and not soaked.  One seed emerged in 35 days, so far.
              [attachthumb=3]

Comparing my methods and results to yours in general, it appears to be the scarification that's the key, not the soaking.  I don't soak any pea family seeds (or any other seeds with exception of a few drops of GA-3 solution for gentians), yet get comparably rapid germination.
