Native to the Sonoran Desert of Baja and the Pacific Coast of Mexico, the spines of Hairbrush Cactus were once used to make a comb. It grows in a columnar branching shape and has nocturnal white blooms that open after sunset and close by midday. In the wild it can become quite massive, but it’s slow growth makes it manageable in the landscape and it is unlikely to exceed a moderate size in one person’s lifetime. Adaptable to heat and drought, Hairbrush Cactus does not thrive in areas with high winter rainfall.
