when do christmas cactus bloom naturally

Christmas cacti, or Schlumbergera bridgesii, are native to the coastal regions of Brazil. They naturally bloom around mid-winter, typically from November to December, but their exact blooming time may vary depending on the climatic conditions of the location they are growing in. In the northern hemisphere, they are known as Christmas cactus due to their blooming season, but in the southern hemisphere, they bloom in the summer. In horticulture, they are often referred to as Schlumbergera x buckleyi, which is a hybrid of Schlumbergera truncata and Schlumbergera russelliana
