This succulent has spectacular flower and I wonder what it is. I thought it was a schlumbergera but now think not - the leaves are not right for that. The flower started as a whorl and a day later opened out, about 3" wide and 4" long,a beautiful reddish colour.

I think Christmas cactus have smaller leaves, one atop the next. This has large ones, tho' with similar jagged edges.

Whilst I don't know what it is I would agree not a Christmas Cactus as we have several of those.
