I hope I posted this in the right forum. It has been impossible for me to get my hands on any South American tubers. And all of the neem seed I have ordered came dry and didn’t germinate after 100s of seed and multiple techniques. I know it is fairly easy to get all of these plants in America through cultivariable and neem nurseries, but none of them will ship to Canada. I hope I’m not on a wild goose chase here. Any Canadian vendors or private backyard merchants around who are blessed enough to have these plants?

Did you try these folks, see if they'd ship to CAN? I got my mashua tubers and yacon plant from them last year, all are doing well. And you know WA is not far.

Yacon  is available from Flora Exotica in Quebec. I think they ship Canada wide on most items.

Thanks a lot. I am also trying to find mashua. And if anyone knows a source for neem I would be very happy.

I don't know about mashua or neem, but for seeds in general, I try to spread this link around:

Talking to the people selling similar products might lead you somewhere, since they'd have an idea of what's out there and how to get it.  I've dealt a little with Flora Exotica and they seemed friendly and helpful.

This US operation has a long list of South American root cultivars. Great tuber selection for anyone in US. They do ship seeds to Canada but varieties are somewhat limited. Maybe they will select unlisted seeds for certain varieties if you speak with them.
Good Luck

Thanks a lot everyone. I’ll tell you how it goes.

Hey Zach,

Where are you located?  If you are in/near Vancouver I have some Yacon that I've overwintered and is sprouting.  I could spare some.
Did you ever find Mashua?

Cheers.
