This is in NB:

I've heard they spread really quickly, but are VERY rich in potassium!

I found another source with

Mapple Farm
129 Beech Hill Rd.
Weldon NB Canada E4H 4N5

wingate@nbnet.nb.ca

They don't have a website yet but will send you a price list via email. I found them on Canadian Gardening website under their mail order catalog PDF file. (Link at top left of the page.)

The yuko.ca site hasn't been updated in a while, so I didn't feel comfortable about the idea of ordering from there. *shrug*

Not too terribly worried about spreading or overpopulation. They will have a large dedicated bed.

I have lots of Jerusalem Artichokes if you are interested in having some, send me an email, I could send you some in a SASE.
