The holiday season has here, which not only calls for decorations but also festive plants! At this time of year, there are many lovely holiday plants to pick from, whether they are bought from a florist, nursery, or are grown at home. The Christmas cactus is one of the most popular plants to give or receive at this time of year. Or is it a Thanksgiving or Easter cactus?
The three cacti differ from one another in terms of how their leaves are shaped. The edges of the leaves of the Thanksgiving cactus (Schlumgera truncata) are very sharply pointed and shaped like claws. The leaf projections of the Christmas cactus (Schlumgera bridgesti) are more scalloped or teardrop shaped. The edges of the leaves of the Easter cactus (Rhipsalidopsis gaertnerrii) are extremely rounded and centered.
These three cacti are all classified as short-day plants. Therefore, the plant needs low temperatures and 12–24 hours of darkness in order to bloom. If you overwintered your plant outside or bought it from a florist or nursery, you should keep it in a cold, dark place until the buds appear. The optimum location is an infrequently used bedroom or lower level. The Easter cactus gets its name from the fact that it takes 8–12 weeks of short days to bloom as opposed to the Christmas and Thanksgiving cacti’s roughly six weeks. It can be brought into a warmer environment once the buds start to form for your enjoyment. At this stage, a plant may occasionally start to lose its buds. That might be caused by air currents, warm temperatures, an abundance of water, or direct sunlight. Bright light is good for the plants, but not direct sunlight. Before watering, the soil should be completely dry to one inch below the surface. Fertilizing or repotting shouldn’t be done when the plant is in bloom. The plants appear to thrive when they are root-bound.
You might see the Christmas and Thanksgiving cactus bloom once more in the spring, though perhaps not as lavishly as over the holiday season. Simply restore the plant to its short day settings to promote springtime blooming.
Unless they are overwatered, these plants are generally disease-free. If the plant turns crimson, there is either too much sun, not enough phosphorus, or not enough water. There are rumors of plants that have been passed down from generation to generation for more than a century. Take advantage of these easygoing holiday plants and establish a new gardening custom.

What kind of Christmas cactus do I have, and how do I know?
Your cactus can be identified by its leaf form. The leaves of the Thanksgiving cactus (Schlumbergera truncata) have sharp protrusions that resemble crab claws. The leaves of the Christmas cactus (Schlumbergera bridgesti) have rounded or teardrop-shaped projections.
What distinguishes a real Christmas cactus from a fake Christmas cactus?
My mother used to refer to her Christmas cactus as a Thanksgiving cactus since it would be fully bloomed by the end of November when I was a child. I was a good boy and never questioned or challenged Mom. Mom was correct, and that was twenty or so years and a couple advanced degrees later. Schlumbergera truncata, the well-liked plant that is currently showing up in garden centers for the holiday season, is also known as the Thanksgiving or false Christmas cactus.
We must delve farther into the passionate love affair with the Christmas cactus in order to overcome this deceit. When we turn the clock 177 years back to 1840s England, we find William Buckley, a committed gardener, and his experiment of a Schlumbergera hybrid between two species. He combined S. truncata with S. russelliana to produce the S. x buckleyi hybrid, which was known as the real Christmas cactus. As you read this at home, you might be tempted to quickly explore the internet. If you do, you might find some outdated literature that refers to this cross incorrectly as S. bridgesii, which would add another degree of dishonesty. There are certainly some older works of literature that use Zygocactus as the genus.
You need to know a few more things at this point because you are horrifiedly staring at your fake Christmas cactus and unsure of where to look for the real one. You need to know a little bit about botany and it is difficult to pick out the imposters. The Schlumbergera’s “leaves” are actually flattened stalks known as cladophyll (phylloclades by some botanist). The faux Christmas cactus will have stems with an open branch habit and soft points or teeth around the borders. These points are simply a part of the stem that is heavily lobed; they are not spines. False Christmas cactus flowers will be cheerful and vibrant in hues of pink, white, peach, and salmon. They will be held for around 5 to 7 days at the tip of the stems, pointing slightly upward. Additionally, the blossoms will appear somewhat horizontal or flat. The stems of the genuine Christmas cactus will significantly arch downward and have a closed habit. The stems will have rounded edges with tiny, discernible points or nubs. The blossoms of a genuine Christmas cactus will be more spherical than those of an impostor, point downward, and follow the stem’s orientation. Reds, pinks, and carmine will be the colors.
You might come across the Easter cactus Rhipsalidopsis gaeteneri, a close relative of Schlumbergera as you go out on your quest to find the genuine Christmas cactus. You’ll be relieved to learn that they are rarely provided and have little financial significance in the garden retail sector. Additionally, as their name suggests, they bloom in the spring. However, if you do come upon one, what’s another plant, right?
Last but not least, I’m sure you read this article and only glanced at the genus name since, like me, you find it difficult to say (shlum-BER-ger-uh), and I doubt that did anything to assist. Just some quick information The Cactaceae family of real cactus includes the Schlumbergera, which thrives in environments that we typically do not connect with cacti. They inhabit trees like orchids and are found deep within South America’s tropical rainforest.
Wishing you luck on your exploration and do let me know if you add a genuine Christmas cactus to your collection.
What three varieties of Christmas cacti are there?
Thanksgiving cactus, Christmas cactus, and Easter cactus are the three popular holiday cacti, each of which is called after the season in which its blooms occur. All three are straightforward to cultivate and have comparable growth patterns and maintenance needs.
Today’s holiday cactus variations are available in magenta, pink, scarlet, as well as yellow, white, orange, purple, salmon, and apricot, however these well-known cacti are typically only available in red-hued hues. The Thanksgiving and Christmas cacti are tropical rain forest species, while the Easter cactus is indigenous to Brazil’s natural woods. All three are endemic to Brazil.
How can you tell whether a Christmas cactus is a certain color?
One of the most vibrant flowering houseplants is the Christmas cactus. When the days become shorter, this low-maintenance plant blooms and puts on a spectacular display over the holiday season. Christmas cacti come in a broad range of hues, including pink, red, crimson, orange, gold, cream, and white, as well as bicolors, in which a single flower displays many hues simultaneously.
This easy-to-grow flowering houseplant has been a beloved holiday decoration for many years. In fact, a lovely Christmas cactus has evolved into something of a family heirloom, being handed down down the decades.
Christmas cacti are magnificent holiday plants when they are in bloom, with their vibrant flowers shining like diamonds at the ends of their stems. Christmas cacti display jagged foliage when not in flower the rest of the year, lending credence to one of their other common names, crab cactus.
Nota: The Christmas cactus is sometimes referred to as the Thanksgiving or zygo cactus.

Christmas Cactus Growing Instructions
For the most blooms, grow Christmas cacti in direct sunlight. It may also grow in low or medium light, however the darker it gets, the less blossoms this beautiful houseplant produces. Christmas cacti can tolerate direct sunlight on their leaves inside.
When the top inch or two of the potting mix get dry, water the Christmas cactus. In comparison to fall and winter, spring and summer are when it prefers a little more water.
Christmas cactus should be fertilized with a houseplant-specific fertilizer in the spring and early summer. For information on how much fertilizer to use and how frequently to apply it, refer to the instructions on the product container.
Christmas cactus requires ordinary to high humidity because it is native to tropical rainforests. While Christmas cactus can handle low humidity levels, you might discover that it thrives and blooms more when the humidity is higher.
The Christmas cactus thrives at ordinary temperatures, although milder fall temps of roughly 55F (13C) can encourage it to bloom.
A genuine Christmas cactus is what color?
A cactus species known as Schlumbergerabuckleyi has fleshy, spinless stems that are separated into flat, leaf-like segments with scalloped margins. The stems first extend upward before sagging downward as they grow longer. On the terminals of the stalks, trumpet-shaped blooms with slender petals appear. They are up to 3 inches (7.5 cm) long, brilliant magenta-red to pink, and bilaterally symmetrical.
Are genuine Christmas cacti uncommon?
In this blog, I’ll discuss how to distinguish between Christmas and Thanksgiving cacti as well as share a link to a video I made for my Cacti & Succulent You Tube Channel called Desert Plants of Avalon in which I go into greater detail about the distinctions between Christmas and Thanksgiving cacti as well as Easter cacti.
Christmas and Thanksgiving cacti are epiphytic cacti that normally grow in tropical rainforests hanging from trees where they receive more moisture and shade than their desert sun-loving siblings. They are members of the Schlumbergera cactus family.
Schlumbergera cacti usually flower from mid-October to late-January, but it’s not uncommon for these cacti to bloom at other times of the year as well, especially if they’re cultivated indoors with artificial lighting.
Schlumbergera buckleyi, the real Christmas cacti, flower later than Schlumbergera truncata, the Thanksgiving cacti that are more frequently seen for sale. Schlumbergera buckleyi (Christmas cactus) blooms from early December to late January, while Schlumbergera truncata (Thanksgiving Cactus) blooms from early October to late December.
The Thanksgiving cactus, Schlumbergera truncata, is also known as the crab cactus because of its stem segments’ crab-like edges (see diagram below). Because of this, Schlumbergera truncata is frequently called the crab cactus.
Schlumbergera truncata, also known as the Thanksgiving Cactus, comes in a wide range of colors thanks to the numerous hybrids that are currently on the market. This cactus is the one that is most frequently seen for sale around the Christmas season and is also mistakenly referred to as the Christmas Cactus when it is actually a Thanksgiving Cactus.
Schlumbergera truncata has blooms that are more upright and do not hang down like Schlumbergera buckleyi.
The actual Christmas cactus, Schlumbergera buckleyi, has stem segments that are flattened and have smooth, scalloped edges rather than teeth ( see diagram below ). These days, this cactus is extremely infrequently offered for sale in garden centers and nurseries, and if you have lately purchased a cactus marked as a “Christmas Cactus,” it is almost always a truncata and not a buckleyi.
The actual Easter Cactus is Rhipsalidopsis gaertneri, and it likewise has stem segments that are highly spherical with scalloped edges, hairy coverings at the tips of each segment, and frequently red edges ( see diagram below ) Easter cacti typically bloom from March to April and their flowers are also significantly smaller.
Here is a video I did for my Cacti and Succulent You Tube channel called Desert Plants of Avalon where I go into great detail on how to distinguish between Christmas, Thanksgiving, and Easter Cactus.
In the coming days, I’ll be creating a blog post and a video on how to take care of Christmas and Thanksgiving cacti, so keep an eye out for them.
From the entire Emerald Isle, I’m sending you all my love, happiness, and an abundance of PLANT POWER.
