This plant is fantastic as all Didiereaceae. I have one from 4 years ago. Very difficult to keep in my climate, it looses all leaves in winter and don't grow again until late summer. Last winter I almost lost my plant. Several frost killed the basis. But this summer I cutted it and replanted and it rooted very easily starting again to show leaves.
