This is really a western species that is represented by var. vivipara at the most eastern edge of its range in west-central MN. It is extremely cold hardy and is the only pink flowering cactus that I know of that naturally occurs as far north as Canada. This plant is one that I grew in southern NY and it managed to get through an entire winter outdoors and still manage to bloom in the spring. Unfortunately it eventually succumbed to wet weather. Attempting to grow this or other cacti so far north and east requires an extremely well-drained soil. Would probably do quite well in an unheated greenhouse.
