Thanksgiving Cactus (Schlumbergera truncata)
The Thanksgiving cactus’ leaves can be used to distinguish it from the Christmas cactus. The leaf segments, or “phylloclades,” have pointed spines and are serrated or “toothed,” with 2-4 on each side.
Because of this, these succulents are known as “Crab Claw Cactus.” The final segment’s end has a point on either side and a little concavity.
Thanksgiving cactus flowers are created at the tips or the point where the leaf segments converge. They look like a long tube, like a flower inside a flower.

The Christmas cactus (Schlumbergera x buckleyi) and its cousins don’t exist in hot, arid conditions like deserts or plains, in contrast to other cacti.

- While the plant is in bloom, it’s very crucial to water thoroughly.
- Feed your indoor plants with a balanced houseplant fertilizer every two weeks from spring through early fall. Feed the cactus once a month in the fall and winter to promote fruitful blooming.
- To promote branching and more flowers, prune plants in the late spring. Simply cut a portion of each stem off; the plant will grow new branches from the incision.
