Christmas cactus, scientifically known as Schlumbergera spp., is a group of epiphytic tropical plants originating from South American rainforests. These delightful plants make excellent houseplants, and with the right care, they can bloom reliably year after year, adding a touch of festive cheer to your home.

Your Christmas cactus will thrive when placed in indirect sunlight, grown in organically rich, well-draining potting medium, and watered only when the top layer of soil feels dry to the touch.
