Cylindropuntia tunicata, commonly known as sheathed cholla and also referred to as Brown-spined Hudson pear, is a perennial shrub that is part of the cactus family. It is native to arid and semi-arid regions, specifically the Chihuahuan Desert of North America. This cactus typically grows in open areas, desert grasslands, and rocky slopes. It can reach heights of 3 to 5 feet (0.9 to 1.5 meters) and has a distinctive appearance with segmented branches covered in a sheath of tan to brown spines that can be up to 3 inches long.

Sheathed cholla is known for its resilience in harsh desert conditions, requiring minimal water and thriving in well-drained sandy or gravelly soils. It prefers full sun exposure. The plant produces greenish-yellow flowers that bloom in late spring to early summer, adding a splash of color to the landscape. However, its spines are a significant concern as they can cause injury to humans and animals and damage equipment. In cultivation, it is used primarily in xeriscaping and as a barrier plant due to its spiny nature. Gardeners should handle it with care and plant it away from high-traffic areas. It is considered an invasive species in Queensland, Australia, where it affects agriculture by invading pastures and natural areas. It has been found to become invasive in Queensland, Australia, harming livestock and damaging tires.CC BY-SA 4.0
