Santa Rita Prickly Pear (Opuntia santa-rita): Purple-Padded Desert Beauty

Overview

Santa Rita Prickly Pear (Opuntia santa-rita) is a stunning, shrubby opuntia with round, flat pads that turn a vivid violet-purple in response to cold and drought stress. The purple is most intense in winter. Pads are spineless or have few spines, but glochids are present. In spring, bright yellow flowers with red centers bloom at pad edges, followed by purple-red fruit. Native to the Southwest US and Mexico, it's cold hardy and extremely drought-tolerant. A showstopper in xeric gardens and containers.
