  Before anyone thanks or applauds me for the list, presuming someone might want to.... It was actually compiled by a friend of mine..... though i did take about 45 minutes copying and pasting each link individually.    he had them as names and they showed up as names only instead of links when i first copied them.

What a great resourse! I think this kind of thing is very important. I just wish I had the $ to buy and breed more seeds.

Thank you! this is the kind of resource that everyone with a backyard/kitchen garden should have access to. I know it was your friend who compiled this list but if you have any that you would reccomend (i live in New Orleans LA) please don't be shy to do so.
Cheers!
