I'm hoping someone here has some of these seeds to trade.
As far as I know they are only distributed by Burpee's, who does not ship to Canada. Their Canadian affiliate store does not carry them.
I would love to hear from you if you have any to trade. I keep my trade list up to date on gardenweb. Here's the link:
