You could just go to middle Tn. plant swap. I could fix
you up with some.

Marianna's Seeds has an amazing selection of heirloom tomatoes, peppers, and eggplants, and some herbs too. I think she sells seedlings through May--i picked up some seedlings a few weeks ago and they are vigorous and healthy. Not exactly cheap, but worth it IMO. She's in Dickson -- http://www.mariseeds.com

I would love to go to the plant swap but sadly I live near lynchburg which is about 2 hours away from it and were leaving at 4am that sunday for the mountains, I don't think my kids would fo gor that much car time. As I was reading I was drooling. I would love to go. I'm new to plants and don't have a huge variety in fact I was going to bring aloe babies cause thats all I have outside of strawberries, Thank ya'll for your response. C Smith
