Seed Starting Chronicles 2014

Sorry this thread is a bit out of date, and I can't find one for 2013 and it's a bit late to start one now.

 

I have seed from one of the Exchanges of wild collected Clintonia uniflora and would welcome advice on when to sow and cultivation generally please.

(Moderator note: I've started a new thread, David, I hope successfully!  How about let's include "late 2013" in with the 2014 thread?    Lori)

David, I have sown seeds of different Clintonias at once when I get them and store the pots either in a cold frame or outside during the winter. Usually they germinate the first spring or sometimes the second.

Here they like a shady (but not dark) woodland setting.

The first germination is always exciting!

Ligularia soldanella started germinating Jan. 21, after 9 days at room temperature.  

What a pleasure to start seeds from Alplains, with excellent and accurate seed starting instructions right there on the packet!  I grew this years ago and planted a couple out - one overwintered and emerged, never to be seen again.  If you scroll down to the bottom of this link, you'll see it's worth another try:

Edraianthus graminifolius 'Alba' - first sprout on Jan. 23 after 11 days at room temperature.

 

Convolvulus tragacanthoides - first sprout after 13 days at room temperature.

Acantholimon alatavicum - first sprout after 4 days at room temperature.

Wow, that's an amazing Convolvulus. Looks like its growing in a desert-like region in China.

Yes, indeed!

The seeds I'm growing from it were collected by M. Holubec in Kyrgyzstan, from either Kyzyl Tu, Terski AT, ("semi-desert steppe")  or Kyzyl Ompul, Kyrgyz AT ("2200 m, rocky slope").

When you say "at room temperature" ?

Do you mean under lights? as well?

Hi, Caroline!  

"At room temperature" means just that and once things start to germinate, the fluorescent lights are turned on.  (I just put a thermometer under the lights among the trays and it does indeed show 70 deg F.  :-)  )

Also, I would normally add if there had been some treatment prior to germination, e.g. stratification (and for how long) or scarification.  So, to be clear, the seeds that have just germinated are easy ones that just need moisture and a little warmth.

Three Lilium species, all hypogeal germinators.

  Planted at 65-70F.  When I saw no germination at 25 days, I move them to 60F.  They began germinating almost immediately.

 

Lilium ciliatum

 

Lilium monadelphum

 

Lilium martagon var. cattaniae

Very nice, Rick!  That was an initial 25 days at a cold temperature, right?   

I'm trying Lilium lophophorum... probably pointlessly, oh well.   I have planted them and have them in the cold room.  Any advice would be appreciated.

 

A few more eager beavers over the last couple of days:

Eritrichium aretioides - germination after 13 days at room temperature.   (Again, excellent documentation from Alplains.)

Aster batangensis - germination after 4 days at room temperature

Aster vvedenskyi - germination after 5 days at room temperature

Gypsophila cerastioides - germination after 7 days at room temperature; I'm starting over with this one, as somehow the old plants that I moved have never regained vigour (probably due to broken tap roots, I suppose?)

Astragalus coccineus - germination in 4 days at room temperature after scarification.  (NB.  I do realize that germinating this species is easy - it's growing it that's hard!  Here's one more try... )

No.  They have always been in warm (65-70F to start).  It's hard to know for sure that the lowering to 60F did the trick, or if they were ready to sprout anyway.  I have other lily seeds in the same regime with no germination yet.  I don't think that there are any Lilium spp. that actually germinate in the 40F ( 4C) range.  Although, many do require such a temp for some time before and/or after germination.

I tried some 3 year old lophophorum seed from NARGS seedex last season.  No luck, but there was only one or two seeds with detectable embryos.  I am going to try again this year with seed harvested in 2013 from two sources.  From what I read, they would like your general regime to germinate in, but to keep them going they apparently prefer cooler temps (60F-15C).  Also important to keep them drier once germinated.  Not exactly sure what that translates to.
