Blind Pricklypear

Opuntia rufida is a multi-branched cactus that may reach 3 to 5 feet (0.9 to 1.5 m) tall and a bit wider. The plant generally has a short trunk, and the thickish, tomentose pads are subcircular, obovate, or elliptical. Areoles are spineless but have showy red-brown glochids. In mid-spring the plant produces a profusion of brilliant yellow flowers changing to orange and red, 3 to 4 inches (8 to 10 cm) across. In summer, the oblong fruit is bright red to purple, 2 to 3 inches (5 to 8 cm) long. The plant can be a spectacular addition to the desert garden. It requires full sun and is highly tolerant of desert heat. However, the glochids tend to dislodge easily when the plant is bumped or shaken and they can be dangerous to humans and animals if carried by the wind. In fact, the common name blind prickly pear or cow blinder refers to the blinding of animals by the airborne glochids. The species rufida refers to the ruddy, reddish-brown glochids.

Opuntia rufida is native to the Big Bend area of southwestern Texas and the Chihuahuan Desert of northern Mexico.
