Plant Details

Some of the species described here originate in the desert Southwest and Mexico; others are native to those areas and/or to other parts of the western U.S., the Great Plains, Canada, and Florida. Many kinds, with varied appearance. Most species fall into one of two sorts: those having flat, broad joints (pads) or those having cylindrical joints. Members of the first group are often called prickly pear; those in the second group are frequently known as cholla and now placed in the genus Cylindropuntia. Pods that break off and fall to the ground root quickly and hasten the plant's spread. Hardiness is variable, but all require excellent drainage. Flowers are generally large and showy. The fruit is a berry, often edible.

  • Bears yellow to orange, 3- to 5 inches-wide flowers in late spring, early summer.
  • Blossoms are followed by roundish, 2- to 312 inches-long fruit that ripens from yellow to red; these are the prickly pears used in Mexican cooking you may see sold in grocery stores as nopales.
  • Handle them carefully; the bristles break off easily and irritate the skin.
  • Wear rubber gloves when peeling the fruit, or impale it on a fork and carefully strip off skin, avoiding bristly areas.
  • This species is very drought tolerant, but in the hottest regions it will need regular moisture for best fruit.
