Description
Opuntia ficus-indica is a shrubby cactus that slowly grows up to 16.5 feet (5 m) tall. The root system spreads horizontally. Stem segments are very thick, fleshy, oblong to spatulate, up to 2 feet (60 cm) long, and up to 10 inches (25 cm) wide. The epidermis is very thick and waxy, thus very water repellent and sun reflecting. Flowers are bright yellow to orange-yellow and open in the late morning. Flowering occurs on 1- to 2-year old stem segments. The edible fruits are fleshy, reddish, ellipsoid, and up to 3 inches (7.5 cm) long.

Hardiness
USDA hardiness zones 8a to 11b: from 10 °F (−12.2 °C) to 40 °F (+4.4 °C).
How to Grow and Care
Though the large variety of species within the Opuntia genus means different Prickly Pears may need slightly different care. All are desert cacti that need lots of sun, light, and very little water. So if you live in a hot, arid area, these plants can generally be planted outside, left alone, and enjoyed.
These cacti will grow just fine in a garden, but they can also be grown in pots. To repot, ensure the soil is dry, remove the pot and knock away the old soil. After treating any cuts with fungicide, place the cactus in a new pot and backfill it with potting soil. As with a new cutting, make sure not to water a newly repotting Prickly Pear for a brief period to avoid rotting its roots.
Opuntia can propagate either by cuttings or by seed. To propagate by cuttings, sever pads from a plant and let them dry so that the wounds heal. Then place the plants in dry soil and refrain from watering them until they begin to grow to avoid rotting them.
