Did you check the Exchanges forums here? There are several of them - a general exchange and vegetable seed exchange etc. but you'll most likely find them over on the Tomato Exchange linked below. I know both Seed Savers Exchange and Territorial Seed as well as several other seed companies carry them if all else fails. Dave Here is a link that might be useful: Tomato Exchange forum

i would also like to get some ground cherry seeds. drawing a blank on unique perennials for zone 5, but check my list and see if you would like to trade for something there. Here is a link that might be useful: leila's list of seeds for trade

I would love to trade for your Bell Pepper Yellow and Fresh Pineapple Ground Cherry. I do not have what you have listed on your 'wants' but have just collected Tigger Melon seeds and Deep Red hollyhock seeds and swapped double pink hollyhock seeds. Peggy

I would love to try the ground cherries. Did you like the taste of them? I'm trying to imagine a tomato/pineapple flavor (from my googling..lol) and I just can't imagine it! Thanks! Wendy / sassyb.
