A cholla is a spiny, branching cactus native to the deserts of North and South America. The genus Cylindropuntia contains about 35 species, ranging from low shrubs hugging the ground to small trees reaching 3 meters (10 feet) tall. Chollas are best known for their cylindrical stems that break apart at the slightest touch, earning some species the nickname “jumping cactus.”
What Makes a Cholla Different From Other Cacti
Chollas belong to the same subfamily as prickly pear cacti, the Opuntioideae, and for a long time they were grouped together in the genus Opuntia. The key difference is shape: prickly pears grow flat, paddle-like branches called cladodes, while chollas grow cylindrical, radially symmetric branches called joints. That cylindrical form is what gave the genus its name, Cylindropuntia.
Beyond shape, the two groups differ under the surface. The tough outer tissue layer beneath the skin is about twice as thick in prickly pears as it is in chollas, which partly explains why cholla joints snap off so much more easily. All chollas share one defining feature with prickly pears: tiny bristles called glochidia tucked into each areole (the small bumps where spines emerge). These bristles have backward-facing barbs that make them almost impossible to brush off bare skin.
How the “Jumping” Trick Works
Chollas don’t actually jump. But the illusion is convincing enough that hikers swear the cactus leapt at them. What really happens is mechanical: the joints are only loosely attached to the parent plant, and the spines are extremely effective at grabbing onto anything that brushes past. A slight touch is all it takes for a spine to puncture skin or clothing, and the joint snaps free from the plant before you can pull away.
Researchers at the University of Illinois examined jumping cholla spines under a scanning electron microscope and found they look remarkably similar to porcupine quills. Both have overlapping layers of microscopic barbs that act like tiny sharpened blades, concentrating stress on animal tissue so the spine slides in easily. Those same barbs then catch on muscle fibers, making removal far harder than insertion. The result: the spine penetrates with almost no force but resists being pulled out, so a whole chunk of cactus rides away on whatever animal (or person) triggered it.
This is not an accident. It’s a reproductive strategy. Those hitchhiking segments can root and grow into new plants wherever they land. Chollas reproduce through seeds as well, but vegetative cloning through detached joints is faster and more reliable. Fallen joints root most successfully during warm months when nighttime temperatures stay above 60°F.
Where Chollas Grow
Chollas are concentrated in the Sonoran, Mojave, and Chihuahuan deserts, spanning Arizona, New Mexico, southern California, Nevada, Texas, and northern Mexico. Different species occupy different elevation bands. The cane cholla (Cylindropuntia spinosior), for example, grows between 2,000 and 6,500 feet in desert grasslands, flats, and valleys. Beyond North America, other species extend into South America and the West Indies, though the greatest diversity is in the southwestern United States and Mexico.
Common Species You’ll Encounter
Of the roughly 35 species, a handful dominate the desert landscape:
- Jumping cholla (Cylindropuntia fulgida): The most notorious species. A tall, tree-like cactus reaching up to 10 feet, with cylindrical stems covered in dense white-to-yellow spines. Also called chainfruit cholla because its fruits hang in dangling chains that persist for years.
- Teddy bear cholla (Cylindropuntia bigelovii): Looks deceptively soft and golden from a distance, thanks to a thick coat of pale spines that catch the light. Up close, it’s one of the most painful chollas to brush against.
- Cane cholla (Cylindropuntia spinosior): Common in higher-elevation grasslands. Produces vivid pink, red, or yellow flowers and has a woody internal skeleton that artisans sometimes use for lamps and walking sticks.
- Buckhorn cholla (Cylindropuntia acanthocarpa): Named for its antler-like branching pattern. Widely distributed across the Sonoran and Mojave deserts.
Flower colors vary across species, from inconspicuous chartreuse to vivid magenta and orange. Most bloom in spring or early summer.
Why Chollas Matter to Desert Wildlife
The same spines that punish hikers serve as a security system for desert animals. Cactus wrens build their bulky, globe-shaped nests almost exclusively in dense stands of cholla and prickly pear, preferring plants taller than about 75 centimeters (2.5 feet). The spines deter predators like snakes and roadrunners from reaching the nest, and the cactus structure creates a cooler microhabitat inside, which matters when ambient temperatures exceed 110°F.
Wrens use these nests year-round, not just for raising chicks but also for nighttime roosting by adults. They often build several nests within a single patch of cholla, rotating among them. Other animals benefit too: packrats pile cholla segments around their dens for protection, and woodpeckers excavate holes in the larger tree-like species. The fruits provide food for javelinas, desert tortoises, and various rodents.
How to Remove Cholla Spines
If you brush against a cholla and end up with a segment stuck to your skin, resist the urge to grab it with your bare hand. You’ll just transfer the spines to your fingers. The most effective first step is a hair comb or any stiff, flat edge: slide it under the segment and flick it away from your skin. Pulling straight out can drive barbed spines deeper.
Once the main chunk is off, individual spines will remain embedded. Use fine-tipped tweezers or needle-nose pliers to pull each one out from the base, following the same angle it entered. Wear gloves if you have them. After removing the spines, clean the area with soap and water. Tiny barbs can break off beneath the skin and cause irritation for days, so check the area again the next day and remove any remaining fragments.
Prevention is simpler: stay at least a foot away from any cholla, and watch where you step. Detached joints litter the ground around mature plants and are just as capable of latching on as the ones still attached.
