Cholla (Cylindropuntia genus)

This profile represents Cylindropuntia at genus rank. [Kew](https://powo.science.kew.org/taxon/1114108-2) accepts the genus. No species, cultivar or planting material is chosen, and no common dimensions, hardiness, water need or measured fire performance is assigned to every member. ## Colorado CSU/CSFS — July 2025 source context The [2025 fact sheet](https://csfs.colostate.edu/wp-content/uploads/2025/08/CSFS_CSU-Ext_Fact-Sheets_IRLP_2025_081825-2_web_accessible.pdf), page 5, prints Cylindropuntia spp. / Cholla with ignitability score 8 under Native low-water shrubs and cacti. The source places this row in its native low-water shrubs and cacti section; that heading does not establish native status or one water need for every member. Modern Opuntia and its separate source row are not treated as equivalent to this cholla genus. This is a qualified documentary association at the printed generic-name scope. The source's intended biological circumscription, particular planting material and individual-member assessment are not resolved by this profile or its tag. In the source's scale, 10 is least ignitable. Its site, size and water cells remain source context rather than universal genus traits. Identify the actual plant before choosing placement; follow the source's spacing, watering and dead-material-removal guidance. No plant is fireproof. Keep other regional sources and ratings separate.
