The two plants can be differentiated by looking at the flattened stem segments, called phylloclades.
Note that there are no true leaves on either of these cacti.
In the Thanksgiving cactus, the stem segments have pointed or hook-shaped projections along the edges.
The Christmas cactus has more scalloped or step-like projects.
Although it is a true cactus, the plants do not grow under the conditions commonly associated with cacti.
They are epiphytes, meaning they grow on other plants, such as in the crooks of tree branches.
As houseplants, Thanksgiving cacti prefer a loose, well-draining growing medium.
Thanksgiving cacti do well when a little pot bound.
Repot plants only every two to three years.
Flowering is triggered by the shorter days and cooler nights of autumn.
What is a plant lover to do?
Do not expose the plants to artificial light after sunset for six weeks beginning in the middle of September.
Maintain air temperatures in both locations between 60F and 68F for optimal bloom.
If you do not have a “dark room” try placing your Thanksgiving cactus in a cool window.
Cool temperatures can sometimes override day-length requirements.
Be careful not to expose plants to temperatures below 50oF, which can cause bud drop.
