Holiday Cactus

I'm not great with houseplants, but these Holiday (Christmas) cactus and I have always got along. My mom had several which she ended up giving to me (when I still lived in Scotland). The plants themselves were not pretty, but the flowers were always lovely.

I was lucky to get this white-flowered one. The day I went to the store to buy one, a couple of years back, I got there when there was only one left. It sits between my pink-flowered one and my pink-and-white-flowered one. I think I should always have at least one of these in my house.
