Summary: The holidays always put us in the mood to spruce up our homes, and one way to do that is with houseplants. Few houseplants outside of orchids flower, but two that do so very colorfully are Christmas cactus and Christmas kalanchoe. Christmas cactus (Zygocactus) is a common sight in garden centers this time of year, usually sold in 4- or 6-inch containers. The color of the flowers covers an impressive range from pink to red to orange to coral to white.
