Cylindropuntia is a genus of about 20 cacti native to Mexico and the American southwest. They are primarily shrubby or groundcover cacti, but can also grow tree-like. These cacti are highly segmented with many joints separating their cylindrical stems, and their spines are known for being quite nasty. Previously, the Cylindropuntia genus was classified as a subgenus of Opuntia, although they have since been separated.1 Still, you will see some varieties of Opuntia commonly referred to as cholla cacti as well. Cholla cacti are some of the most common cacti growing naturally in deserts across the southern United States and Mexico.
Cholla cacti are known for being hardy, and as long as you can provide them with lots of sunlight, they will be pretty happy. If there is one thing to stay away from when it comes to growing cholla, it’s moisture. These cacti are highly drought-tolerant and can easily succumb to overwatering, especially if they aren’t receiving enough light.
