Description

The Purple prickly pear cactus is a colorful species with rich plum-purple coloring on young pads. Over time it can grow 4-5 ft. tall, 4-5 ft. wide. Short bristle-like spines cover pads and fruit; bright yellow flowers contrast boldly against its purple pads from later winter into spring.

Purple prickly pear provides more foliage color than most species of Opuntia and is commonly planted as a color accent plant in Southwestern style plantings and for display in containers. It is well adapted to sun, heat, aridity and summer drought.

Water Needs

Purple prickly pear is well adapted to all parts of the Inland Empire in sunny exposures with normal winter rains and low amounts of summer irrigation. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains often provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates Purple prickly pear can grow with varying amounts of water; little supplemental water is needed during summer following the flowering cycle.
