Yes, Christmas cactus (Schlumbergera bridgessi) do typically bloom every year, but they don't necessarily bloom during the holiday season. They are a popular houseplant and are known for their showy, colorful flowers that appear during the winter months. The blooming time can vary depending on the variety and the conditions in which it is grown. In general, they will start to flower in late fall or early winter and will continue to produce flowers for several weeks. Some varieties may bloom more than once a year, while others may only bloom once.
