How do I hook up with a Trader?!! :)
I've been collecting n growing houseplants for over 20 years. I own a hundred houseplants including exotic cacti, and begonias. I live in Ontario, Canada, if that matters. :)
Yes, your living in Canada probably would matter to U. S. traders, since sending plants to other countries can get complicated--with the necessity for phytosanitary certificates and etc. I've purchased roses from Canada, so I know it's possible, though probably easier for nurseries.
If you don't have any luck with the Dave's Garden Plant and Seed Trading Forum, you might want to search the member list for other members from Canada--and then look at their trade lists. Or you could check out the Canadian Garden Exchange at GardenWeb, though I doubt it's very busy at the moment. Most exchange sites slow down during this time of year.
