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.CC BY-SA 4.0
