This is a pic of the window it has lived in for the last 5 years. I’d say it’s about 30 inches wide. My friend has one that is a decent amount larger but he has had it outside in the summer and in a larger pot. Mine has been confined to a smaller pot and treated like a succulent because I just assumed that it would grow the same way for whatever reason by being root bound and stressed a little with infrequent watering.
