Some good success shown there folks.
Here's a few different genera sown at different depths last month ,germinating after being placed outside unprotected.
Lilium oxypetalum var insigne --seed surface sown.
Myosotis capitata ---surface sown.
Crocus biflorus ssp isauricus sown just under the surface --i scraped away a little of the mix to see what was happening....
Ornithagalium sigmoideum sown deep.
Arisaema griffithii sown deep after chilling for 5 weeks. Thumb is shown to give an idea of the seed pots.
I'll move them under cover at the end of the month to keep them going over winter.

I continue to be seduced by seed . ;D
I understand Saxifraga longifolia is not that difficult to germinate so as an experiment last month i surface sowed half of a 'swap' on pumice and the other half on peat/grit and placed them outside .
Other than the different mixes both pots were given identical ,(as much as i could control),conditions ,each placed in a plastic bag which was tied --however after a week because of the amount of the condensation i left the bags open with the plastic ,stiff ,well above the sides of the pot to try to continue giving them a settled atmosphere.
So far the results have been interesting .
The pumice pot is showing advanced germination compared to other one.
Followed by a couple of macro shots showing the seed in various stages of germinating on and between the rock . Cheers Dave.
Dave, have you tested other seeds on pumice?
Several seedpots have germinated the last week and now I hope for higher temperatures!Trientalis borealis germinated after 2 winters outside. Seed from Kristl Walek. I am not quite sure of the difference between this and the European T. europaea though!
Rogaland, Norway - with cool, often rainy summers (29C max) and mild, often rainy winters (180 cm/year)!
Forgot to say that the big plant in the previous replay is a weed! But surely you did understand that!
Here are something new that has germinated: Mistletoe (Viscum album). Got berries from a forumist on SRGC this spring and squeezed the seed onto several rowan and linden stems. A lot of them have germinated but climbing snails have found them irresistible! Hope some survive.
Dave, have you tested other seeds on pumice?
At the same time i sowed the Saxifraga above , as a continuation of the experiment i also sowed half of a portion of Ramonda and also in another pot,Physoplexis, under the same conditions on pumice and the other half sown on peat/grit with all pots placed outside in plastic bags ....... --none of those pots have sown any activity yet.
I think you win the prize for most unusual angiosperm seedling, Trond. 8)

Thanks Dave, please keep me (us) updated on your pumice experiment!
Rick, I hope I get some to reach more than the seedling stage!
Allium carinatum ssp. pulchellum planted 7 Feb inside for 2 weeks, then placed outside where they emerged on 30 April. 30 April 2013 22 May 13
Draba polytricha planted in Late May 2012, one seed emerged in 10 days and eventually withered. These emerged 6 May 2013.
Iris lutescens planted 30 Jan 2012, emerged 17 May 2013.
Lilium nanum ex Sikkim and Lilium nanum var. flavum both emerged on the same day after 3 weeks at 60-65F under lights, then 2 weeks outside in varying temps of 40-80F and lots of rain.
Penstemon nitidus planted fall 2011 emerged 14 May 2013. I planted two lots from the same batch: one with seeds that were planted as received, the other I rubbed between my fingers to remove the superficial covering and reveal the true seed before planting. So far, only the rubbed seed has come up. P. cobaea seed, natural and rubbed. P. nitidus
Penstemon speciosus wild collected in Nevada. Planted 3 Feb 2012, emerged 13 May 2013. A few more had germinated, but only one left...
Veronica fruticans (thanks Trond!) from Myking, Norway. Planted 3 Feb 2012, emerged 17 May 2013. Our 2012 spring started a month early so they only had a month of cold conditioning in 2012. Apparently that wasn't enough.
Cardiocrinum cathayanum. I was given a copious amount of seed as the percentage of viable seed is said to be very poor. So I had literally covered the soil surface with seed as I planted in spring 2011. The first seeds germinated in our very unseasonably warm March 2012. But didn't last long. Knowing they wouldn't be winter hardy here, the pot went into the fridge the following fall and another germinated in the fridge (by 9 April 2013) when I got around to placing them outside. What was interesting was that the soil was (accidentally) bone dry! Amazing! The rest came up in eight days and warmer temps (and watering!). No sign of the original seedlings.
Colchicum hungaricum. Planted 15 March 2011, these went through two natural warm and two natural cold cycles to emerge 15 May 2013.
Crocus speciosus planted 5 Feb 2012, and again only a month of cold conditioning, emerged 8 May 13.
Mertensia ciliata (Thanks Lori!). Planted 3 Feb - outside temps, emerged 1 May.
Silene hookeri planted 7 Feb at 60-65F, then in fridge 17 March, then outside 4 May. Emerged 15 May.
I really like this topic, fascinating to see how people have sown their seed and see the results. I take the lazy man's approach, sowing seed out in the garden for some items, and for others (equally as lazy) sowing in flats and letting mother nature do the work over winter and spring. Here's some things germinating recently, the non-stop pouring rain for the entire last week certainly helps germination along, suddenly many Arisaema are showing.
I've had Carex appalachica for almost 10 years, one of the best species, with thread-fine foliage and tiny yellowish flowers that create a haze of tiny "points of light", I have yet to capture an adequate photo of it. No seedlings have ever appeared, so I sowed seed collected from my plants last summer, they're coming up. It's very slow growing (and expensive to buy), so I'm glad for the increase.
Iris lactea and an Arisaema sp., both collected in the Himalaya by Chris Chadwell. Pleased to get such good germination on the Iris. On Arisaema, I had about 5 species all show germination just this week, they are typically late-emerging seedlings.
Lindelofia stylosa Cc7161 (Chris Chadwell seed from the Himalaya), needs transplanting soon.
Iris cristata - seed from mixed named forms 2012, these were planted out yesterday (in the rain), about 30 seedlings.
Epimedium grandiflorum f. flavescens 'Nanum' - my seed 2012, all will be hybrids. Last year I was traveling to Dallas TX for my work, for a little over a week, and missed much of the Epimedium seed ripening. Even so, I have about a dozen and a half Epimedium varieties germinating.
Arisaema sikokianum, just starting to germinate, sown in a large plastic salad/lettuce container (I ran out of my preferred peat flats last autumn, resorted to re-using grocery containers such as this, and blue styrofoam mushroom "flats" seen in some of my other shots. My Arisaema seed were sown "whole berry" rather than being cleaned; each berry has 2-5 seeds in it. Many more seedling coming up since I took this photo last week.
Jeffersonia dubia (two flats front to back), and J. dubia "Korean Form" on the left (back), with 2nd year plants of Diphylleia grayi on the left.
Glaucidium palmatum white form, on the right, and one seedling so far of Clintonia andrewsiana on the left (hoping for more); thank you NARGS Forumists!
