Now and then I've picked up holiday cactus and keep them growing. I just sit them outside in partial sun for the summer and bring them back inside for the fall. Last winter I took cuttings. They are not up to blooming yet. Very easy - just cut off stems and stuck them together in fresh potting soil. These really help when it's so gloomy outside. I have one more making buds, salmon colored that I started from cuttings ten years ago.
