What is Beavertail Cactus
Beavertail Cactus Overview
Opuntia basilaris, the beavertail cactus or beavertail prickly pear, is a medium-sized to small prickly pear cactus species found in the southwest United States with pink to rose-colored flowers.
A single plant may consist of hundreds of fleshy, flattened pads.
They are typically spineless, but have instead many small barbed bristles, called glochids, that easily penetrate the skin.
Each areole supports many glochids but are usually without spines.
Opuntia basilaris blooms from spring to early summer.

ADAPTATION FOR SURVIVAL
Flat, wide pads with thick “skin” to hold moisture.
Pads covered with tiny, hair-like spines.
Be careful of this cactus, as the tiny spines work into the skin and are very difficult to see and remove.
Cactus fruits and pads are important food for many desert animals, especially woodrat and jackrabbit.
Indians cook both fruits and pads after removing their spines.
