Description
Consolea rubescens, formerly known as Opuntia rubescens, is a tree-like, almost spineless cactus with a cylindrical trunk and flattened, spreading or descending branches with lateral paddles. It grows up to 20 feet (6 m) tall. The trunk grows up to 8 inches (20 cm) in diameter and has reddish or grayish brown, peeling bark. Paddles are lance-shaped, oblong, or elliptic, with wavy margins, and up to 20 inches (50 cm) long. They look like they have tire tracks across them, hence the common name "Road Kill Cactus." The areoles are up 0.8 inches (2 cm) apart and bear tiny, yellowish, woolly fibers and deciduous brown glochids. Spines can also be present, usually between 6 and 12. They are grayish and up to 1.2 inches (3 cm) long.
Flowers are up to 1.2 inches (3 cm) in diameter, yellow, turning orange with age, and appear in spring. Fruits are green, flattened-obovoid, with persistent spines, and up to 2.4 inches (6 cm) long.
Hardiness
USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Though the large variety of species within the Opuntia genus means different types of prickly pears may need slightly different care, all are desert cacti that need lots of sun, lots of light, and very little water. If you live in a hot, arid area, particularly the American Southwest, these plants can generally be planted outside, left alone, and enjoyed.
Though Opuntia will grow just fine in a garden, they can also be grown in pots. To repot, ensure the soil is dry, remove the pot, and remove the old soil. After treating any cuts with fungicide, place the prickly pear in a new pot and backfill it with potting soil. As with a new cutting, ensure not to briefly water a newly repotting prickly pear to avoid rotting its roots.
