Overview

This North American cactus spreads into low clumps of flattened stem pads, which carry tiny barbed bristles called glochids. True leaves are small and short-lived; the pads remain green. Yellow flowers appear in summer, followed by reddish berries. Winter shrivelling is normal, but stagnant wet soil causes rot.
