I made the leap and ordered my seeds on line from Seed Savers Exchange. They are totally awesome, almost everything is certified organic, and totally heirloom. No hybrid seeds here!
I ordered just about everything except the sweet corn and lettuces. I want to go with a brand that has more common types of lettuce and corn for me to plant. I am by no means nearly an expert, and I dont want to go crazy trying to pick out what I think looks good. I will probably go with some sort of hybrid sweet corn and easy lettuces like leaf lettuces.
