I think this plant is called a Christmas Cactus but I'm not sure. I have had it for years and it hasn't grown much at all. I've seen the same plant at other peoples homes and they are 5 times the size of mine and some have flowers. I'm not sure if I'm over watering it but I usually wait until it looks like it's a bit droopy before I do. I would like to know what I'm doing wrong. If somebody can help it would be appreciated.
