Just numbers not names! Maybe some new species?
Some are named; in the view above, there is A. caeruleum and A. drobovii, received about 5 different collections of the latter species, which is a species not generally in cultivation... in the following link, click on the paper icon on the far lest of the listing, then click on the thumbnail images... mot a great beauty, but may be interesting nonetheless.

Speaking of patience: I sowed some Actaea pachypoda on 3/08. They are coming up now (4/11). They've been at outdoor temperature (near Portland, OR) all this time, in a slightly moist mix in a shaded place.

I've only just looked through this fascinating thread. Over the years running a small specialist nursery I tried to divide plants into manageable groups that needed different sowing regimes. Generally for a lot of alpines, and quite a few woodland plants our winters are not long and cold enough with snow cover to get really good germination. On those occasions when it is colder and we have prolonged snow we often found much better results. As soon as I see signs of seedlings I bring plants into a frost free greenhouse which warms up quite a bit in the late winter/spring sunshine!
The benefit of our winters though is that we get fluctuating temperatures and this is probably useful for many of the colder Mediterranean and semi-desert species I have tried, where temperatures do not stay so low right through the winter. Lori mentioned Lomatium columbianum earlier on and I have always sown this and other species as early as I have had seed and left outside all winter. Germination is often poor, but at least some come up. Umbellifers in general do much better from reasonably fresh seed sown in the autumn - older seed is usually dead, although I have had Eryngiums germinate well the second season. Once or twice I have gone to the lengths of putting seed (in damp sand) into a fridge for about 4 to 6 weeks. Several species stsrted to germinate in the fridge, including Lomatiums and Eriogonums, but unless you catch them just as they germinate or before they quickly etiolate and are less than easy to deal with. If you grow a lot of different things this quickly becomes very complicated, but it could be really useful for something special that has not germinated well by normal means.
It is great to hear how others get on with sowing seed (I have Deno's books but they become a bit mind-boggling after a time and I have always found it much more effective to use the time tested ways of sowing in pots). Hope I can add to the thread in the coming spring.

I garden in a relatively hot and dry region (for the UK!), with an annual rainfall of around 25", winter lows of -10°C and summer highs of 30°C.
I typically rely on the tried and true seed germination method of allowing Mother Nature to make germination happen, leaving the pots or flats outside for the winter and see what happens in spring. I like using wide peat flats, as I believe the moisture level stays more even than smaller plastic pots.
Here is some germination from varieties that Jane Hendricks generously sent me (thanks Jane!), Senecio pudicus on the left, and Thlaspi stylosum on the right, but only two seedlings of Allium brevistylum... maybe more will germinate later.
The flat of Aquilegia saximontana (true) from Jane, I was most anxious to see some germination. The other varieties shown above, germinated early spring, but no sign of life in the flat of A. saximontana... I figured that the seed must have failed. Then one day I noticed some germination, a few tiny seedlings. Now it is thick with seedlings, must have gotten 100% germination. I shouldn't watch seed pots every day, it's like waiting for water to boil or watching grass grow. ;D
I have planted out my seedlings of Thlaspi stylosum today! I don't need to water, it is more likely they drown :-\
Mark - I know what you mean about watching seed pots; its one of those exciting spectator sports that no-one else can understand! Your epimedium beds look spectacular too - here the combination of rabbits and drought haven't done them much good but wushanense does grow well. I think they are even more popular in the States than in the UK. My special love has always been Jeffersonia dubia, and a pot of seedlings of this brings joy to the nurseryman!
I've never said I am a good grower, but I do have some successes. This is hopefully a good overall reference for some of the seedlings that have emerged this season for me. The gibberish after the plant name is formatted: xxxx-yy-zzxxxx=source. If all digits, it's a NARGS seed ex number.yy=year seed was collected.zz=year planted.
A good portion of these are seeds that germinated in the second and even the third season after planting.

Cool seed growing presentation Rick! This is a good example to illustrate one benefit of the way NARGS thumbnail image enlargements work, where it pops up a separate window. Click on the enlargement a second time and it displays at the full large image size (for jumbo-sized images, such as in this case)... now you can move the enlarged-image-window around partially off-screen to simultaneously read the columns of seedling identifications while finding the seedlings in the photo-diagram... what fun to look at all those germinated seedlings. Rick, you have a lot of transplanting to do!
You have good taste Rick, almost the same species as I have sowed ;D But you have control, I have not :( Have been very busy the last weeks and seedlings are growing out of their pots.Too little time to plant them in separate pots.
