Unfortunately given the ag shipping/importing restrictions you will have to buy them from one of the companies that has a standing inspection certificate with Canada. That means extra shipping fees plus the high costs of shipping to begin with. Territorial Seed Company is one that has them and will ship to Canada Tomato Growers.com is another None of the Canadian-based seed companies list them that I can find. Even Tatiana's doesn't list them for this year. Dave

Great sleuthing! I'm also in Toronto, and have found people selling extra Turface on Kijiji from time to time. I wish the Orchiata was cheaper. The west coast distributor sells 40L bags for $33.05. I imagine it is quite expensive to ship it out here. Not sure where they get their douglas fir bark from; it also looks pretty suitable if a bulk source could be had. I tried a bag of that All-Treat Canada Red pine bark mulch from Home Hardware recently. Not a fan. It's shredded, with long, thin particles. Also lots of sapwood.

I live in the Kitchener-Waterloo area and have a hard time with climbing roses too. Sally Holmes is awesome for me. Starts out with a peachy bud, but fades to white. Haven't really noticed much of a fragrance though, Here she is this morning: New Dawn, which I believe is supposed to be zone 4, always dies right back to the snow line. Last fall I defoliated all her leaves, tied the canes together, wrapped it in burlap, lay it on the patio, and buried the entire thing under mulch. It seems to be the only way to get climbing roses to really climb for me. But my goodness, she repaid me kindly. I’ve taken to planting co-ordinating clematis to get the height I want.

Thanks, definitely looks like Ladysthumb / Smartweed after checking out some photos on the internet. http://www.omafra.gov.on.ca/english/crops/facts/ontweeds/ladys_thumb.htm
