Oh no, 3 month late finding this post!
I save sooo many prairie-native seeds, some will end up rotting before I find a home for them. The mice get some. Friends get buckets full of 'em. One confesed he never planted his, fearing seeds from an adjacent prairie state might carry some contaminant (the way firewood carries Emerald Ash borer to every county in the state). *sigh
I even mail seeds - all the way to Spain, in one case, and he mailed me some sweetpea seeds from his second home in Australia in return. And they grew, and blossomed, and I saved the seeds in the fall, but they never grew for me again. And he stopped writing me. (An author. Very accomplished and very private author. No surprise there.)
We have several Seed Sharing groups in our state, but I always forget to contact them... meanwhile, I have lots of gorgeous purple aster seed, some blackberry lily, and this year, not one asculepias tuberosa (orange butterfly) - not sure why that is! They did bloom! Something ate the seed pods?
