Tree Cholla is the tallest cholla cactus, sometimes reaching 15 feet, and is one of the most distinctive plants of the Chihuahuan Desert and southern Rocky Mountain foothills. It produces large, cup-shaped magenta flowers in May and June, followed by yellow fruits that persist on the plant for years. The branching, tree-like form provides protected nesting sites for cactus wrens and roadrunners. It spreads into degraded grasslands, sometimes indicating overgrazing, and forms dense stands on rocky hillsides.
