I decided to do some seed starting under lights again this year (it's been a while), so I printed out the list to mine for stuff that would do well in my garden--86 pages! because the landscape/magnifying glass 21-page version wouldn't come up for me. I suspect your seed from last year will show up around the same time this year's does. At least, that's the way things happen around here. :) Looking forward to seeing your choices.

I mainly ordered seed of native Spring ephemerals;
Trillium
Hepatica
Erythronium (Trout lily, Fawn lily, Dog's-tooth violet)
and a few other natives.
a couple of shrubs;
Hydrangea arborescens (cut-leaf form)
Stewartia (silky camellia)
Daphne caucasica

Also had to include seed of some of my favorite South American Amaryllidaceae, Rhodophiala sp.
and some Cyclamen seed, of course!

You often receive non-viable seed from the exchange, because some seed only retain their viability for a short time after maturity. They are starting a new proceedure this year, recommending that those seed be packaged in damp vermiculite for preservation.

Hope yo are correct, about finding my lost seed! It's very frustrating, knowing they are here, somewhere, and not being able to find them!
