Flowering best in spring an occasional off timing flowering would be in responce to the growing conditions you provide.

Ah :-) of course. I moved it from the east window to the north window, and started watering it more (it was neglected before)

Must've been the extra water

Extremely pretty! These do seem to bloom whenever they feel like it. Add your lovely pic to December blooms?

You have a beautiful plant there..how big is your whole plant? I have a small start. just 3 pads. hope it someday grows enough to bloom...we don't get many "holiday" cacti.....maybe they think we have too many cactus as it is..... hahaha molly / sewnmom7

It's really not very big. Size and shape is like 3/4 of a loaf of bread.
