I have a cactus plant growing here in Ottawa. It lives in a shallow oval bowl, with a base of earth, topped with course sand. It has been out there in full sun for over four years, but at this time every year it has at least two feet of snow over it. This summer we should see it flower, for the first time.
Yes…cactus does grow in the "Cold White North. I also know a couple in Montreal that have a proper Cactus garden, that survives Winter’s wintery blasts. We do get down below -30C…regularly.

I didn’t know that. Cool! I’ve only had them as house plants 'cause I thought they couldn’t deal with cold.
