How To Tell A Christmas Cactus From A Thanksgiving Cactus

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.

How can I determine the type of cactus I have?

The physical characteristics of each cactus should be used as a starting point when distinguishing one from another. Some distinguishing physical characteristics to watch for are:

The Leaves

One essential aspect you may want to consider is the cactus plant’s leaves. Do your plants have any spines? You can determine this by examining their leaves. A leaf with spines will have needle-like, sharp edges, while a leaf without spines will have rounded edges. The color and shape of your cacti plant’s leaves can also provide useful information.

Chlorophyll and carotenoids, which are photosynthetic pigments, can be used to determine the color of leaves. Carotenoids give the plants their characteristic colors, whereas chlorophyll is in charge of receiving light energy from the sun and storing it as chemical energy.

Your cactus plant type may also be determined by the shape of the leaves. Succulent plants often have spines and needle-like leaves, whereas flat-leaved plants are typically stronger in nature since they can endure severe situations better. For instance, the leaves of a barrel cactus grow straight, whereas the leaves of a saguaro cactus are flat.

Similar to the shape and color, the different needle styles can also be used to identify the type of cacti you have, albeit the results are not always reliable. The more hardy and leafy kinds will typically have flat spines, whilst the more succulent and squishy forms would typically have needle-like spines.

How high can they grow?

When determining the type of cactus you have, you might also want to consider its height. Because plants that thrive at higher elevations typically have longer roots than those that do not, height and altitude can be utilized as a determining factor when choosing your plant type. The Saguaro Cactus, which may often reach heights of 50 feet, is the tallest of all succulents. Hedgehog and pereskia, on the other hand, are little kinds that rarely grow taller than six inches. You can tell what kind of cactus plant you have by just measuring the height of the plant.

Shape and coloration

When there are no spines or leaves to go by, a cactus’ shape and color can also be utilized to determine its type. Shape typically gives some hints about the plant’s requirements for the climate, which in turn may give more information about the nature of the plant.

Although there are so many different kinds of cactus that you can identify, you might not be able to do so just by looking at it because of its color. Another spiny variety may have a green-brown body, whereas a white-spined barrel cactus may have green. The dwarf saguaro’s yellowish hue stands out sharply from, for example, the brown spines on a barbed wire cactus.

As you can see, there are a lot of physical characteristics to watch out for that could reveal what species of cactus plant your plants are. One piece of advice is to explore further if you notice something peculiar or unusual about a particular species because it might be what you’ve been looking for.

How are its flowering style and pattern?

The way a plant blooms is another physical characteristic that will reveal whether it is a terrestrial or epiphytic plant. While terrestrial plants have roots and require direct connection to soil, epiphytes are plants that thrive in humid regions with little soil contact and depend on other plants for nutrition.

Another sign of a cactus’ kind is the way its flowers are arranged. The saguaro and barrel both feature radial patterns, while the hedgehog is another plant with radial patterns but more elongated ones. A species that forms columns, like the cardon, may have vertical stripes or zigzags with contrasting color patterns.

The most likely form of cactus you have is a cardon if it is columnar and has vertical stripes of contrasting colors. On the other hand, if your cactus has radial patterns and spines, it is probably either the barrel or saguaro type.

Although it’s not always reliable, the color of the flowers might also give you a hint about what kind of cactus your plant is. For instance, a hedgehog may have yellow blooms, or a kind of flower with a red top may be a cardon.

What about the seeds?

Depending on their environment, different cactus species generate different seeds. For instance, the Saguaro cactus produces smaller, fleshier seed pods, whereas the hedgehog produces much larger, spiky fruit. While the cardon is known to produce seeds that are round and glossy, some varieties, like the barrel cactus, will have a more oval or spherical appearance.

These various seed pod varieties can provide you hints about the kind of cactus you might grow in your garden. Perhaps after a lengthy development period, your plant that you’ve had for a while isn’t blossoming or generating any flowers? Even before planting, it may be quite beneficial to look at the seeds, since they might provide important details about the type of plant. If your cactus isn’t flowering or generating any flowers over a lengthy time of growth, it may not be blossoming due to its type or the climatic circumstances that type loves. Different cactus species generate different seed pods.

Do I have a certain kind of Christmas cactus?

The Christmas and Thanksgiving cacti have different leaves but the same flowers, as was already described. Easter cacti, on the other hand, have leaf margins that are smoother and devoid of notches and require a considerably longer cool and low light period in order to flower. Easter cactus plants have flat, star-shaped flowers that are simple to distinguish from the elongated blooms of the other holiday cacti.

Purple-brown anthers hang from the drooping flowers of the Christmas cactus. The blooms of the Thanksgiving cactus feature yellow anthers and develop parallel to the stalks.

All three plants have different hues, although red to fuchsia are the most typical. They come in white, orange, and yellow as well. No matter what they are called, holiday cactus are rather simple to grow and will bloom every year if they have their low temperature, low light period.

Is it an Easter, Thanksgiving, or Christmas cactus?

The Schlumbergera family includes the Christmas and Thanksgiving cactus, therefore their histories are extremely similar. Both of these are tropical cactus from Brazil’s rainforests. They were found by Allen Cunningham in the early 19th century, and the genus was named in honor of an unusual botanist by the name of Frederic Schlumberger.

Schlumberger has six different species, many of which have special holiday names. Every plant has a name that refers to the season in which it blooms in the Northern Hemisphere. The Christmas cactus blooms a little bit later than the Thanksgiving cactus. However, since they both bloom in their native countries from April to May, neither term is used for them there.

The Hatiora family includes the Easter cactus. You’ll notice the difference in watering later because this succulent is also from Brazil, but it comes from the drier jungles. Sadly, not much is known about how the Easter cactus was discovered. However, the Christmas and Thanksgiving cacti are likely to be in season at the same time.

What kind of cactus celebrates Thanksgiving?

The Thanksgiving cactus (Schlumbergera truncata), a low-maintenance indoor plant that blooms in or near November, is a native of Brazil. A Thanksgiving cactus can be identified by its green, serrated leaves that resemble crab claws and by its crimson or magenta, tube-shaped blossoms that resemble a flower inside a flower. Contrary to its name, the Thanksgiving cactus is an epiphytea plant that grows on other plants rather than a genuine cactus. Thanksgiving cactus frequently sprout from trees in their natural habitat.

Is there a cactus identification app?

The best app for identifying flowers, cacti, succulents, and mushrooms is called PlantSnapi. The program searches through a database of more than 600,000 plants using image recognition software that is powered by machine learning.

Software for automatic pattern recognition powers this. It states that it can detect 99 percent of common species with an accuracy rating of 95 percent. The app’s searchable database also includes more than 10,000 species.

Researchers from Columbia University, the University of Maryland, and the Smithsonian Institution created Leafsnap. It employs visual recognition software to distinguish between different tree species based on how their leaves look. Currently, the app features trees from Canada and the Northeastern United States.

What are the little round cactus called?

Cacti belonging to the Mammillaria genus contain a number of cultivars, including Mammillaria backebergiana ernestii (left) and Mammillaria boolii (right)

A member of the Mammillaria family of cacti, the Powder Puff cactus is a tiny, round species.

A slow-growing type of cactus with soft, hairy spines all over, the Powder Puff cactus has a ball-like shape. The Powder Puff cactus is among the Mammillaria family of cacti that requires the least amount of maintenance. The spherical cactus will reach a height of between three and five (7.512 cm) and a diameter of roughly the same.

The Powder Puff cactus needs lots of sunlight and soil that is never more than mildly damp, as do the majority of cacti. The Powder Puff will often bloom in the summer with white or red blooms forming a crown on top.

Some other well-known cacti created by the Mammillaria genius include the following:

Cactus Mammillaria backebergiana ernestii has a tall, cylindrical shape.

A little, round cactus called Mammillaria boolii has spines that resemble fine hair. The comparatively large flowers that grow on this little cactus are an intriguing aspect of the plant.

The reddish-violet flowers of the Mexican native Mammillaria mystax bloom in April and May.

Identification of the cactus: The Powder Puff cactus can be recognized by its rounded, ball-like shape covered with bunches of sharp spines. The gorgeous flowering plant has a ring of purple, pink, or white blooms that forms a lovely crown when it is in bloom.

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.

What distinguishes Christmas cactus from counterfeit 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.
