Description Christmas Cactus Thanksgiving Cactus Care Guide FAQ/Common Issues Schlumbergera, also called Christmas Cactus, is a tropical cactus in the Cactaceae family native to the cloud forests of southeastern Brazil. Unlike desert cacti, it evolved as an epiphyte clinging to trees in humid, shaded forest canopies. Schlumbergera features flattened, segmented stems with slightly serrated edges that cascade as the plant matures. The segments are glossy and smooth, creating a full appearance that works equally well in a hanging basket or displayed on a shelf. It blooms in late autumn through winter, producing tubular flowers in shades of pink, red, white, and purple at the tips of trailing stems. Cooler night temperatures and longer dark periods trigger blooming, so a seasonal temperature drop is essential for holiday flowers. Schlumbergera is a beginner-friendly cactus that does well in kitchens and bathrooms where ambient moisture keeps it content. It is pet friendly, so no concern with curious cats or dogs. It also releases oxygen at night, making it a thoughtful addition to a bedroom. You can leave it up to ten days without water.

It prefers temperatures between 60 and 70°F and needs a night drop to around 50 to 55°F to trigger blooming. Schlumbergera is a moderate grower that benefits from balanced liquid fertilizer applied monthly during spring and summer. It is hardy in USDA zones 9 through 11, tolerating temperatures down to about 30°F before frost damage becomes a risk. It grows outdoors in Florida, California, Texas, Arizona, Hawaii, Louisiana, Georgia, South Carolina, Alabama, Mississippi, Nevada, and the Oregon coast.
