When you purchase a Schlumbergera in stores, it is called a cacti. Commonly known as Christmas, Thanksgiving, and Easter cacti. These cacti flowers are named after the holiday they bloom nearby. Most stores sell Christmas cacti that are Thanksgiving cacti, so knowing how to tell the difference can be helpful even though all produce beautiful flowers.
Stems:
Christmas cacti stems are less pointy, and they are more scalloped, or teardrop shaped than their cousins. Easter cacti have more rounded leaves, aka stems. The most popular type, the Thanksgiving cactus, has the pointiest leaves, and their edges are more of a claw shape.
Flowers:
Christmas and Thanksgiving cactus produces tubular flowers. Easter cacti have daisy-shaped flowers.
