My grandmother had two of them, and they bloomed beautifully every year. I just read your post this morning, and while I was out looking for an Amarylis, I picked up a Christmas Cactus too :) It's a small one, but it only cost my 4.99 at the florist, I imagine I could have gotten a cheaper one somewhere else, but whatever.
It's on my kitchen table now, I can't wait for all the blooms to open up!
