Schlumbergera truncata (Haw.) Moran is the correct and accepted name for this plant commonly known as the Christmas or Holiday Cactus. It was named and described as such by Reid Venable Moran in Gentes Herbarum in 1953. It was first named Epiphyllum truncatum and described by Adrian Hardy Haworth in Supplementum Plantarum Succulentarum in 1819.

The genus, Schlumbergera Lem., was named and described by (Antoine) Charles Lemaire in Revue Horticole in 1858. Plants of the World Online lists nine accepted species of Schlumbergera.

One of my neighbors gave me this cactus in 2012. We had gotten acquainted because she had a really nice yard with lots of flowers. We also traded a few plants now and then.

Flowering is triggered by a combination of temperature and darkness. Naturally, the day length decreases as cooler temperatures come in the fall. Both are important to trigger buds to develop. Night temperatures between 55-65° F and around 12-13 hours of darkness is ideal. If temperatures rise above 90° F the buds could fall off.

The Schlumbergera truncata likes to fairly pot bound and doesn’t need repotted until after 3-4 years. There are several common names including Christmas, Cactus, Holiday cactus, Thanksgiving Cactus, Crab Cactus, etc. Some think they are all different plants so may have several, maybe because of the different flower color. However, they are all the same species. There are a few different cultivars available.

I gave this cactus to a friend when I moved from Mississippi back to the family farm in Missouri in 2013. I have seen then at the local greenhouses and garden centers but I just haven’t brought any home yet.
