My flat of Anemonopsis, which germinated this spring, is showing some first true leaves, so far on at least 6 seedlings (can you find all 6?).  So, it seems I don't need to wait until the second year to see true leaves.

Mark, I have 3 different batches of Anemonopsis seed germinating now and they all show true leaves now.

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!

Have seen suggestions for germination of Paeonia and Roses on paper towels the latter initially cold and the former initially warm, on wet paper towels.  Some rose people suggested using a solution of 1.5% hydrogen peroxide.

Anyone "stratify" on paper towels?

RickR, your Alyssum stribrnyi seedlings look exactly like Romneya coulteri.

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.

Thanks, Gene.  Years ago, I had a plant of Alyssum stribrnyi and I didn't remember any jaggedy leaves like that either. I'll bet you are right. ;D

I just found a nice thick cluster of Hepatica transsilvanica seedlings under the mother plant. Any suggestions on whether to divide them this year or wait till next spring. They are growing in a very tight group, on top of each other in some circumstances. Only a few have their true leaves yet.

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.

Full of promise ,not far from their first flowering ---- Seed sown June 2009 and potted on once, they don't appear to have suffered from not being separated into individual pots.

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

Cheers Dave.
