Christmas Cacti are easy to grow. When they bloom, they produce colorful tubular flowers in pink or lilac colors. They bloom a long time indoors and they are low-maintenance houseplants, which makes them popular. We’ll bet someone in your family has a Christmas Cactus!
Despite their name, Christmas cacti are not desert cacti. Their natural habit is one of an epiphyte living in tree branches in the rain forest of Brazil! In other words, they prefer a humid climate, not a dry one, so it’s important to water these cacti. (See more details below.)
Also, note that there are several types of holiday cacti: Easter, Thanksgiving, and Christmas. They bloom closest to the holiday of their name. Christmas cacti have flattened leaves with rounded teeth on the margins as opposed to the Thanksgiving cactus that has pointed teeth. Easter cacti have pointed teeth with fibrous hairs in the leaf joints.
To confuse matters further, most of the Christmas cactus sold are actually Thanksgiving cactus. If you find your Christmas cactus blooming near Thanksgiving, guess what?
