Toni -- I don't think people are done with the seed collecting here by any means!! Hope you'll check out the Piggy Seed Swap at Ella's Garden on Cubits -- this is my first year for signing up (although every year I've "thought about it")
I've saved several tomato varieties, several bean varieties, marigolds, catnip, dill, and Baptisia australis (blue false indigo). Next year I'll plan to save more things to share!
