Beavertail Cactus

Opuntia basilaris

The vivid colors of the flowers of the Beavertail Cactus are due to a type of pigment known only in a few plant families. Although the lack of spines on this cactus give the plant a benign look, the Beavertail Cactus is well armored: thousands of hairlike spines, called glochids, are borne in circular patches on the pale blue-green pads.
