The Schlumbergera truncata, sometimes known as the Christmas cactus, blooms from October through January. The species and its variations, sometimes known as the Thanksgiving or holiday cactus, are hardy in U.S. Department of Agriculture plant hardiness zones 10 through 12. Most frequently grown as a houseplant, the Christmas cactus blooms in a variety of hues, including the classic red as well as purple, pink, orange, gold, and white.
How many different hues are there in Christmas cacti?
Did you know that there are cactus for Christmas, Thanksgiving, and Easter? The key variations between various holiday cacti are listed below, along with advice on how to take care of your cactus so that it continues to bloom.
Brazilian forest cacti are the parent species of holiday cacti such the Christmas cactus, Thanksgiving cactus, and Easter cactus. The names of the holidays correspond to the several North American cacti’s blooming seasons!
The Easter cactus is in the genus Rhipsalidopsis, which grows in dry woodlands, while the Thanksgiving and Christmas cacti are Schlumbergera species.
Christmas Cactus
The resilient plant that our grandmothers raised is called the Christmas Cactus (Schlumbergera bridgesii). I have a plant that was developed from a cutting my mother-in-law acquired more than 70 years ago! They are the ideal plant to pass along because they are so simple to root. Simply cut a bit of one of the branches in the shape of a “Y” and place it in a pot of sterile soil or vermiculite. It will quickly begin to root.
Thanksgiving Cactus
The Schlumbergera truncata, sometimes known as the “Thanksgiving Cactus,” blooms normally from mid-November to late December and occasionally even into January. It gets its common name “crab cactus” from the shape of its square leaf segments, which have pincer-like hooks on one end and along the edges. It is indigenous to Brazil, where hummingbirds pollinate its 2 to 3 inch long, satiny blossoms.
Easter Cactus
It may very possibly be an Easter cactus (Rhipsalidopsis gaertneri), which blooms in late winter and spring, often from March to May, if you discover that your holiday cactus has spring flowers.
The Easter Cactus, also known as a “Spring Cactus, features trumpet-shaped, flaring flowers with pointed petals that are typically pink but can also be red, orange, and other cherry colors. Their several-week-long star-shaped petals have an opening at dawn and a closing at dusk. They have segments of flat, succulent leaves.
More Ways to Tell a Christmas Cactus from a Thanksgiving Cactus
A large portion of the plants for sale are hybrid crosses of the Christmas and Thanksgiving cacti (Schlumbergera x buckleyi), which come in a wide spectrum of exotic hues like orange, purple, yellow, red, pink, white, and two-tones.
Look at the flower’s bloom color and flowering pattern:
- The magenta-hued hanging blossoms of the Christmas cactus bloom naturally close to Christmas. Late November until early February is when flowers typically begin to bloom.
- The Thanksgiving cactus comes in a variety of hues and has flowers that face outward. Compared to the Christmas cactus, this plant blooms closer to Thanksgiving. Very late in October or early November, it may begin to bloom.
Additionally, they have various stems:
- The flattened stem segments of the genuine Christmas cactus have smooth, scalloped edges.
- The stem of the Thanksgiving cactus bears two to four sharp teeth.
- The Thanksgiving cactus has stems that initially grow straight before arching, in contrast to the Christmas cactus, whose stems dangle down like pendents.
Because it blooms around the time of the American Thanksgiving, Thanksgiving cacti are what are typically sold in nurseries and retail establishments. The Christmas cactus is also more challenging to export since the stems are more brittle and frequently break.
Caring For Your Holiday Cactus
The holiday cactus is a unique kind of the plant. The Christmas plant, unlike the desert cactus that we are all know with, is an epiphyte that thrives in decaying leaf litter on the branches and in the forks of trees in tropical rain forests in South America.
- Even though the conditions in our homes are nothing like those in the natural rainforest where they live, they are perfectly fine at the typical household temperature of 65 to 70F, with a decrease to 55 to 60F at night. When it is below 40 degrees Fahrenheit, they will require protection.
- You should offer these cactus acidic, well-draining soils because they prefer their forest floor. Add perlite, vermiculite, and orchid bark to a cactus mixture.
- They want bright light but not direct sunlight, so a window facing east or west works best. It indicates too much light if the leaves become yellow. Keep them behind a shade tree or patio if you place them outside during the warmer months. not in direct sunlight.
- Water the plants when the top 2 inches of the soil feel dry, allowing them to dry out between waterings. Avoid overwatering; this is the main cause of their death in our houses. Overwatering is better than neglect! To determine when to water, you could purchase a hydrometer. Keep them out of the water; if they become too soaked, they will rot.
- Frequent misting of the plants increases humidity.
- Optional: Use an all-purpose fertilizer, such as Miracle Grow Tomato water-soluble fertilizer, to fertilize them (1 tablespoon to a gallon of non-chlorinated water). Feed the plant while it is actively developing twice a month (usually spring and summer).
How to Keep Holiday Cactus Blooming
Short days and mild nights are the secret to making your holiday cactus bloom. Before they will begin to set buds, they require 13 hours of darkness and nights that are between 50 and 55 degrees for at least a month or two. Some of my plants spend the summer outside, and I don’t bring them inside for the fall and winter until the temperatures start to dip below 50 degrees. They typically develop a bud right away and then begin to bloom. The plants that I have growing in my kitchen need no particular care, and they still thrive. Why, yes!
Only repot the plants if they are really crowded because they flower best when they are slightly potbound. Don’t be hesitant to bring one home for the holidays because they are non-toxic to cats and dogs, unlike many festive plants.

From April through October, you may help keep the foliage on your Christmas Cactus from becoming purple by using a standard all-purpose fertilizer twice a month.
Because Christmas Cactus requires more magnesium than the ordinary plant, you should apply a teaspoon of Epsom salts every other week. In October, stop fertilizing completely to encourage blooming during the holiday season.
Do you have any yellow Christmas cacti?
The yellow Christmas cactus is a succulent plant that was grown in a soil mixture made especially for succulent plant species that drains effectively.
A white Christmas cactus exists, right?
Bright and indirect light are both beneficial to our White Christmas Cactus. These cheerful wintertime flowers look lovely when placed in a pot of a vibrant color and cheer up indoor spaces. The petals of the flowers face downward and are vibrantly colored. There are many various colors available for Christmas cacti, including yellow, red, white, pink, salmon, and bi-color.
The White Christmas Cactus grows nicely indoors in a space with direct, strong light, such as a window sill in the east or the north. The White Christmas Cactus can tolerate low light levels, but it will blossom more rapidly in bright light. When exposed to ambient temperatures of anywhere between 65 and 75 degrees F and bright, indirect light, the flowers, which are dazzling white, bloom profusely.
The plants prefer to remain in a dryer environment. During the holidays, White Christmas Cactus is stunning, offering a sophisticated white hue with vibrant green foliage.

Why is the purple color on my Christmas cactus fading?
Your Christmas cactus leaves frequently have a purplish hue, which is typical. However, if it is conspicuously present throughout the leaves, it can indicate a problem with your plant. The following are the most typical causes of Christmas cacti’s leaves turning red or purple:
issues with nutrition
Your Christmas cactus may be deficient in essential nutrients if you don’t fertilize it frequently. From spring to mid-autumn, treat the plant every month with an all-purpose indoor plant fertilizer.
Additionally, since Christmas cacti require more magnesium than most plants, adding 1 teaspoon (5 mL) of Epsom salts to 1 gallon of water as a supplement to the plant’s diet usually works well. Throughout the spring and summer, apply the mixture once a month, but avoid using it the same week you apply conventional plant fertilizer.
dense roots
Your Christmas cactus could not be properly receiving nutrients if its roots are bound. This is one potential explanation for the Christmas cactus’ reddish-purple leaves. Don’t repot your plant until it has been in the same container for at least two or three years, but keep in mind that Christmas cactus flourishes with dense roots.
Repotting Christmas cactus is best done in the spring if you find that it is rootbound. Transfer the plant to a container that is filled with a potting mix that drains well, such as ordinary potting soil blended with perlite or sand. The pot has to be one size bigger.
Location
Christmas cactus needs bright light in the fall and winter, but excessive direct light in the summer may cause the leaves to become purple on the margins. It could be possible to avoid sunburn and fix the issue by moving the plant to a better place. Ensure that it is not near any open doors or drafty windows. In the same way, stay away from hot, dry locations like those near a fireplace or heating vent.
How many different shades of cacti exist?
A cactus’ thin, delicate skin can be any shade of green, including light, medium, and dark, as well as gray and almost blue. Although they have a harsh appearance, a cactus’ spines contrast sharply with the rest of the plant and are frequently among its most attractive features.
Why are Christmas cacti’s hues different?
A lovely Christmas cactus with white blossoms was a gift from my son. However, the blossoms were pink the following year. What took place?
Hybrid plants frequently revert to the prevailing hue of the original species. Fortunately, even though the flowers are not the color you ordered, they are still lovely. Keep cultivating it in a sunny area. Reduce water use beginning on October 1st, spend the nights somewhere cooler and darker, and wait to be rewarded with flowers.
What kind of Christmas cactus do I have, and how do I know?
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.
