Thanksgiving and Christmas bring unique traditions that help us tell them apart, but identifying their namesake cactuses can be tricky. Both belong to the genus Schlumbergera and share similarities, yet they have distinct differences.
As the holiday season approaches, understanding how to care for a Christmas cactus is crucial. Knowing how to make it bloom is essential, but distinguishing it from the Thanksgiving cactus is perhaps the most pressing question.
If you're uncertain about which cactus you have, here's what to look for to ensure you celebrate the right holiday with the appropriate plant.
Identifying Thanksgiving vs Christmas Cactus: Major Differences
“When identifying these plants, start by examining the leaves,” advises a gardening expert. “The primary distinction lies in their leaf shapes.”
The Thanksgiving cactus, Schlumbergera truncata, features sharp, claw-like edges, while the Christmas cactus, Schlumbergera bridgesii, has smoother, scalloped leaves resembling teardrops.
“Thanksgiving cactus leaves can be described as spiky, whereas Christmas cactus leaves are more rounded and soft,” the expert continues. “Additionally, Thanksgiving cactuses bloom in deep shades of red or purple, while their Christmas counterparts typically produce white, pink, or red flowers.”
Blooming times offer another way to tell them apart.
“Thanksgiving cactuses usually flower in late fall, around November, just in time for the holiday. In contrast, Christmas cactuses bloom during winter or early spring, mainly in December,” notes a houseplant enthusiast.
As they mature, the plants also differ in shape. “Christmas cactuses tend to trail and droop as they grow, while Thanksgiving cactuses maintain a more upright appearance,” she adds.
Thanksgiving cacti are available at Walmart.
Common Questions
How can I identify which Schlumbergera cactus I'm purchasing?
Many retailers label both varieties as "holiday cactuses," which can be confusing. Always check the label for the botanical name. If it's missing, the leaf shape will be your best clue.
Are there similarities between Thanksgiving and Christmas cacti?
Yes, these plants share numerous similarities. Beyond their looks, their care requirements are quite alike. Both need dark periods to set buds and bloom during the holiday season.
If you moved your Schlumbergera outdoors during summer, it's time to bring it inside. Keeping your Christmas cactus in darkness will encourage blooming just in time for the festivities. For optimal growth, consider learning how to repot a Christmas cactus to maintain its health and vibrant appearance year after year.
