History

Illustrated historical scene for Santa Rita Pricklypear

Opuntia santa-rita, commonly called Santa Rita prickly pear or purple prickly pear, is a spreading shrubby cactus native to the Sonoran Desert of southern Arizona, southeastern California, New Mexico, and northern Mexico (Sonora, Chihuahua), particularly the Santa Rita Mountains from which the epithet derives. American botanist Joseph Nelson Rose described it in 1908. Some authorities treat it as a form of the variable Opuntia violacea.

Plants form spreading shrubs 1-2 meters tall composed of round, flat, obovate 10-20 cm pads that in good growing conditions are soft blue-green but in winter cold, drought, or strong sun flush brilliant purple, magenta, or red-purple—the color change is reversible but the species is prized specifically for this dramatic seasonal display. Large glossy golden-yellow flowers 5-8 cm across appear along upper pad margins in spring, followed by 3-4 cm red-purple edible fruit. One of the most popular ornamental Opuntias in Xeriscape landscapes.

Long used by the Tohono O'odham and Hohokam peoples for fruit and pads. Now a defining plant of Sonoran-style landscape design in Tucson and Phoenix, where its purple winter color provides a unique seasonal show. Carries fine irritating glochids despite minimal spines.
