Hi all- I’ve had this cactus for over twenty years... when I bought it, it was shaped like a little stick and has grown that way. I’m the last decade or so I moved to a south east facing apartment and keep it outside in the summer - it’s just exploded! I don’t know what kind of cactus it is- so I’m hoping to find that out- as well as if I can take cuttings and root a much smaller version of this monster. As a side note I bought this at South Bay Cactus Farm in Prince Edward County, Ontario but haven’t been able to get in touch with them.
Looks like a Cylindropuntia of some kind, growing in low-light conditions... Home Cactus Cylindropuntia plant cultivation nature growth
