Prickly pear cactus (Opuntia humifusa) is a unique groundcover that can grow up to 2 feet high with a spread of several feet at maturity (Photo 1). It gets its name from the spines that dot the surface of its wide flat stems. These stems, called pads, contain clusters of spines which provide protection from grazing animals. One maintenance issue is the difficulty in removing weeds from between these spiny pads. Photo 2: Close up of a prickly pear cactus flower (Credit: Steve Yergeau).
