Conditions Comments: Purple prickly pear is similar in form and provides the same rugged accent as the more common prickly pear (Opuntia lindheimeri) known in Central Texas. Its violet-lavender pads separate it from the other prickly pears. Purple prickly pear, like most prickly pear species, will grow easily; you only have to protect it from freeze, as severe cold can kill them. Minimum temperature 45F.
BenefitWarning: Care should be taken in handling this plant, since the minute, tufted, barbed bristles (glochids) at the base of the spines can be more troublesome than the spines typical of most cacti; they are lined with backward-pointing hooks, making them nearly impossible to remove from the skin.
