I've been collecting seeds from Asclepias sp. and Cardinal flowers (Lobelia cardinalis) and some native lily species. The native lily seeds were contained in berries so I removed the pulp and sowed them. The Asclepias seeds require 30 days stratification and I don't want to sow them 'til the end of winter. I've read that the seeds of Asclepias sp.and many other natives species (native to mid Atlantic states) need to be fresh to achieve a decent germination rate but what is the definition of "fresh"? If I store them in a ziplock bag in the fridge until Jan will that be ok or should I be doing something else? How do you store your native plant seeds? Thank-you!
