Varieties of Christmas cactus
Of course, there's the Thanksgiving cactus (Schlumbergera truncata) and the Easter cactus (Schlumbergera gaertneri) to consider. They round out the holiday plant offering and are named for when they flower.
The Thanksgiving variety is sharper-looking, with teeth atop each wide segment. The Easter cactus is rounder and has daisy-shaped flowers, unlike the other two, which have tube-shaped flowers. You'll also notice that Easter cacti have fibrous hairs.
