Here are some purple heirlooms that are available for share or swap http://theseedlibrary.com/catalog/r44.

what do you want to swap?

My current list is at
http://ohiorivervalleyculinaryseedswap.blogspot.com/

I update as I mail or receive seeds.

Sure. I'd be interested in some sugar pod snow peas and/or leeks. What quantities are you thinking? I could only trade about 20 beans. Would you be interested in anything else listed here?

20 beans work. where do I send peas and/or leeks?

My email is DefineAproblem@gmail.com
