Opuntia basilaris Engelm. & J.M. Bigelow
Beavertail Pricklypear, Beavertail Cactus
Cactaceae (Cactus Family)
USDA Symbol: opba2
Flat, grayish-green, leafless, jointed stems in a clump, lack large spines and have vivid rose or reddish-lavender flowers on upper edge of joint. Beaver-tail cactus is a low-growing prickly pear, 6-12 in. high, with brilliant, majenta flowers. The pads of this cactus lack the long, straight spines of other prickly pears but are covered with miniscule, gray-blue bristles with barbed tips.
The gray-green stems, low growth, and brilliant flowers, which often nearly cover the plant, make this a popular ornamental in hot, dry climates. It need not be dug up; a joint broken from a plant will quickly root in dry sand. Opuntia with flat joints are called Pricklypear; in the Southwest, if the fruits are juicy and edible, they area called tuna by people of Spanish-American heritage.
