Are Thanksgiving cactus and Christmas cactus the same thing? Learn more, with helpful photos!
Published: December 11, 2024 | Updated: September 16, 2026
If you've ever admired a burst of colorful blooms around the holidays and wondered what kind of cactus could possibly flower in winter, you’re not alone. The Thanksgiving cactus plant often sparks confusion. Not just because of its name, but because it's frequently mistaken for its holiday cactus cousins.
Are Thanksgiving cactus and Christmas cactus the same? It’s a common question, and to make things even more puzzling, the Easter cactus sometimes gets thrown into the mix too.
But don’t worry. I’ll show you exactly how to tell them apart, with side-by-side pictures of Thanksgiving cactus vs. Christmas cactus and Thanksgiving cactus vs. Easter cactus.

The Thanksgiving cactus plant, known botanically as Schlumbergera truncata, hails from the cool, misty rainforests of Brazil. Unlike the typical cactus you might picture baking under a desert sun, this species grows high up in trees or clings to rocks, soaking up humidity in its lush, tropical home.
Forget spines and needles! This cactus has smooth, fleshy, segmented stems that resemble leaves. These flattened segments, known as cladodes, are easy to recognize by their jagged, pointed edges that look like tiny claws. This is one of the key traits that sets it apart from its rounder, softer-looking relatives.
Adding to its charm, the Thanksgiving cactus bursts into bloom from November through January (and sometimes again in spring), showing off trumpet-shaped flowers in shades of pink, red, orange, white, and even golden yellow. This bloom time helps to distinguish it from the Christmas cactus, which begins flowering a few weeks later.
Another helpful clue? Its upright, more rigid growth habit. While Christmas cacti tend to droop with a cascading, trailing form, the Thanksgiving cactus stands a little taller, with a more structured silhouette.
In this article, I’ll take a closer look at Thanksgiving cactus care, including light and water requirements, soil preferences, fertilizer, and common issues to watch for. I’ll also share tips for choosing a healthy plant and getting your Thanksgiving cactus to bloom. Then, I’ll show you how to tell Thanksgiving, Christmas, and Easter cacti apart with helpful ID photos and side-by-side comparisons.

Thanksgiving Cactus Care
A Thanksgiving cactus is very easy to care for and does well as an indoor houseplant.
It prefers bright, indirect light. Avoid direct sun, which can “sunburn” the stems and cause them to turn purple.
Water every 1 to 2 weeks, when the top inch of soil feels dry. Do not let the soil dry out completely, and make sure the pot has drainage holes.
Pruning isn’t necessary unless you would like a bushier plant. Prune in late winter, after flowering has finished, by pinching off stem segments with your fingers or cutting them with sharp, clean scissors.
Thanksgiving cactus also does well when slightly root-bound. Being root-bound means that a plant's roots have grown densely within its pot, leaving little room to expand. You may notice roots circling inside the pot or becoming tightly packed.
There’s no need to repot a Thanksgiving cactus frequently. I generally recommend repotting every 3 to 5 years, or when necessary because the plant has outgrown its pot or the potting mix has broken down.
With proper care, Thanksgiving cacti can be extremely long-lived houseplants. Some are passed down through families for generations.

Thanksgiving Cactus Soil
In their native habitat, Thanksgiving cacti are epiphytes, growing on trees or rocks rather than in soil. Epiphytic plants cling harmlessly to other surfaces and draw moisture and nutrients from the air, rain, and organic debris.
To recreate those conditions indoors, give your Thanksgiving cactus a well-draining, free-flowing potting mix. I use about 80% cactus potting soil blended with 20% perlite to keep the roots airy and healthy.
Always choose a container with drainage holes to avoid soggy soil and root rot, and let the mix dry slightly between waterings. With good drainage and the right soil mix, your Thanksgiving cactus will have what it needs to thrive.
I use a simple mix of about 80% cactus potting mix and 20% perlite for my Thanksgiving cacti. The added perlite helps keep the mix loose and well draining.
Thanksgiving Cactus Fertilizer
During spring and summer, feed your Thanksgiving cactus regularly to support healthy growth. I recommend an all-purpose, water-soluble houseplant fertilizer such as Jack’s Classic All Purpose 20-20-20, which provides a balanced mix of essential nutrients.
Dilute the fertilizer according to package directions and apply it once a month during the active growing season. Stop fertilizing as fall approaches and the plant begins preparing to set flower buds.

Thanksgiving Cactus Problems
One of the most frequent problems I see with Thanksgiving cacti is that they often come in decorative foil wrappers, which many people leave in place. While these wrappers look festive, they can prevent excess water from draining properly.
When water collects inside the wrapper, the pot may sit in standing water, which can lead to root rot, wilting, and yellowing stems. To avoid these problems, remove the foil wrapper or make sure you empty any excess water that collects inside it after watering.
You can place the plastic nursery pot on a saucer to catch excess water. If you prefer a more polished look, place it inside a decorative cachepot, removing it to water and allowing it to drain completely before putting it back.
Why Is My Thanksgiving Cactus Turning Purple or Red?
If your Thanksgiving cactus is turning purple or reddish, take a look at its growing conditions. A change in stem color can be a sign of stress.
Light: Too much direct sun can cause the stems to develop a reddish or purple color. Thanksgiving cacti prefer bright, indirect light, so move the plant away from harsh sunlight if needed.
Watering: Both overly dry and waterlogged soil can stress the plant. Water when the top inch of soil feels dry, and always use a pot with drainage holes.
Temperature: Extreme temperatures can also stress Thanksgiving cactus. Keep the plant away from heating vents, cold drafts, and hot, direct sun.
Nutrients: If the plant has not been fertilized or repotted for a long time, poor nutrition may contribute to discoloration. Feed with a balanced houseplant fertilizer during the active growing season.

Why Is My Thanksgiving Cactus Wilting and Drooping?
Overwatering: Too much water can lead to root rot, which can cause the stems to wilt and droop. Let the soil dry slightly between waterings.
Underwatering: If the soil becomes too dry, the stems may look limp or shriveled. Water thoroughly at the sink until excess water drains from the bottom of the pot.
Poor drainage: If water can’t drain freely, the roots may remain too wet. Always use a container with drainage holes, and never let the pot sit in standing water.
Wrong soil: Heavy potting soil can hold too much moisture around the roots. Use a loose, well-draining potting mix.
Low light: A Thanksgiving cactus grows best in bright, indirect light. If your plant is in a very dark location, move it to a brighter spot away from direct sun.
Why Is My Thanksgiving Cactus Dropping Buds?
Temperature swings: Cold drafts or sudden changes in temperature can cause buds to drop. Keep the plant away from heating vents and drafty windows.
Inconsistent watering: Letting the soil become too wet or too dry can stress the plant and lead to bud drop.
Low light: Too little light while buds are developing can contribute to bud drop. Bright, indirect light is best.
Relocation stress: Moving or frequently repositioning a Thanksgiving cactus while it is budding can cause some buds to drop.
Natural cycle: A few dropped buds can be normal, especially as the plant progresses through its blooming season.
Why Is My Thanksgiving Cactus Turning Yellow?
Overwatering: Too much moisture can lead to root problems and yellowing stems. Let the soil dry slightly between waterings, and never leave the pot sitting in water.
Underwatering: Soil that stays too dry for too long can also stress the plant and cause yellowing. Water thoroughly when the top inch of soil feels dry.
Poor drainage: A pot without drainage holes can leave the roots sitting in soggy soil. Always use a container that allows excess water to drain freely.
Nutrient deficiency: If your plant has been in the same potting mix for a long time, a lack of nutrients may contribute to pale or yellow growth. Feed with a balanced houseplant fertilizer during the active growing season.
How To Make a Thanksgiving Cactus Bloom
The Thanksgiving cactus is a reliable bloomer, rewarding you with gorgeous flowers year after year. Many people find that their Thanksgiving cactus reblooms without any special effort.
Whether your cactus flowers every year depends largely on the conditions in your home, including temperature, light, and its proximity to a window. Some lucky folks simply keep their cactus in the right spot without realizing it, and voila! Blooms appear! But if your plant seems stubborn, don’t worry. There are tried-and-true methods that can help coax those buds into action.
If your Thanksgiving cactus needs a little encouragement, some intervention might be in order, though the techniques can sound a bit like elaborate pranks on your poor cactus!
For about 6 to 8 weeks, give your plant cooler temperatures, ideally around 55 to 65°F, along with 14 hours or more of continuous darkness each night. During the day, return it to bright, indirect light.
To create these conditions, you can move your Thanksgiving cactus to a cool room where it receives long periods of uninterrupted darkness at night. Or go the DIY route and place a box over it every evening. Yes, it might feel a little ridiculous, but it works!
Once buds begin to form, you can return the plant to its usual spot and enjoy the flowers.
To encourage your Thanksgiving cactus plant to set buds like this, give it 14+ hours of darkness each day in a cool space like a closet or garage. It’s the secret to a spectacular flower show! Image © Plant and Bloom Design Studio
When Can I Buy a Thanksgiving Cactus?
Each year, beginning in late October or early November, Thanksgiving cacti become readily available at plant shops, local nurseries, grocery stores, and big box garden centers.
Plants are typically shipped to stores heavily budded and ready to flower, or already in bloom.
Thanksgiving cacti are also frequently mislabeled and sold as Christmas cacti. True Christmas cactus is less commonly available in most retail settings and can be harder to find.
If you’re looking for a true Christmas cactus, check independent garden centers, specialty plant shops, online nurseries, or marketplaces like Etsy. Just be sure to look closely at the stem segments to confirm that you’re getting the plant you want.
Thanksgiving Cactus vs Christmas Cactus
Are Thanksgiving cactus and Christmas cactus the same? It’s easy to confuse the two because they have similar appearances and care requirements. However, there are a few key differences that make them fairly easy to tell apart:
Stem segments: Thanksgiving cactus (Schlumbergera truncata) has pointed, claw-like edges along its stem segments, while Christmas cactus (Schlumbergera × buckleyi) has smoother segments with rounded, scalloped edges.
Bloom time: Thanksgiving cactus typically begins blooming earlier, often in November, while Christmas cactus generally flowers later, closer to Christmas.
Flower form: Thanksgiving cactus flowers tend to have a more upright or outward-facing appearance, while Christmas cactus flowers are more pendulous and hang downward from the stems.

Thanksgiving Cactus vs Easter Cactus
Are Thanksgiving cactus and Easter cactus the same? It’s a common mix-up! These two holiday cacti may look alike at first glance and share similar care needs, but there are a few distinct differences that make them easy to tell apart once you know what to look for.
Stem segments: Thanksgiving cactus (Schlumbergera truncata) has segmented stems with pointed, claw-like edges, giving it a sharper, more angular appearance. Easter cactus (Rhipsalidopsis gaertneri) has rounded segments with smoother edges.
Flower form: Thanksgiving cactus flowers are tubular and asymmetrical, while Easter cactus flowers are star-shaped with thinner petals that radiate outward from the center.
Flowering time: Thanksgiving cactus typically begins blooming in late fall, while Easter cactus flowers much later, usually in spring around March and April.

Is Thanksgiving Cactus Poisonous to Cats or Dogs?
If you’ve recently been gifted a Thanksgiving cactus or bought one on impulse, you may be wondering whether it is toxic to cats or dogs and if it’s safe to have around your furry companions.
The great news is that Thanksgiving cactus is considered non-toxic to cats and dogs. So if you’re plant obsessed (like me), you can go ahead and get one in every color. 😜 I currently have 6 Thanksgiving cactus plants and 4 rescue pets. Don’t judge.
Thanksgiving cactus also doesn’t have the sharp spines found on many other types of cacti, making it a much friendlier choice for a home with curious pets.
Of course, it’s still a good idea to keep an eye on pets around houseplants. Eating plant material can cause stomach upset even when the plant itself isn’t considered toxic. Contact your veterinarian if your pet eats a large amount or develops symptoms.
For more pet safety information, see my guides to plants toxic to dogs and houseplants toxic to cats.
