I'm not into those, but ediblelandscapingsc is.
There are 255 "HAVE" plants in ediblelandscapingsc's plant list, and many look edible. He's Zone 7, though.
Anyway, I see his name in both currently-organizing seed swaps:
http://garden.org/apps/swap/
You might want to contact home about seed trades, or join one of the swaps. Group swaps are great because you only pay postage twice, but might get 100 varieties of seed in return.
And anyone offering unusual seeds like you have is highly appreciated.
