VPSEN Vancouver Plant and Seed Exchange network. Connecting local gardeners with an appreciation for plant diversity. Trade Plants and Seeds online http://vanseedtrade.theforum.name
Good idea -- we don't really do seed and plant exchanges on a one-to-one basis here on these forums except through private messages (though we do help people promote local plant swaps and meet-ups). Stickied it in this forum, as it is the most likely place people will look for such a service.
cheers, just getting the word out, ive been dropping this in a few key places where people would be interested.
Another organization you may wish to contact (if you haven't already done so) is Seeds of Diversity Canada.
