These little South African succulents always surprise me when they bloom. I never seem to realize there is a bud getting ready to open, and then there it will be. They bloom in the fall here since they originate below the Equator and their seasons are not the same as ours.
Be careful with these plants. I think overwatering is what you have to be careful about. I have had this one for a while and it seems to be doing well, but I will have to admit I have lost a few. But they are worth your time and attention, and there are many varieties to try.
