Overview
Prickly pear (Opuntia) is a large genus of flat-padded cacti, of which Opuntia ficus-indica is the best known for its edible pads (nopales) and sweet fruit (tunas). The plants form sprawling, shrubby to tree-like clumps.
The jointed segments, called pads or cladodes, are actually modified stems that store water and carry out photosynthesis. They are armed with large spines and tiny barbed bristles called glochids that detach easily into skin.
Exceptionally tough, prickly pears tolerate heat, drought, and poor soil, and some species are cold-hardy enough to survive freezing winters.
How to identify it
- Flat, oval to round paddle-shaped pads (cladodes) joined in branching chains
- Pads bear scattered areoles with large spines and tufts of tiny barbed glochids
- Large, showy flowers in yellow, orange, pink, or red in spring and summer
- Fleshy, often red to purple fruit (tunas) following the flowers
- Can range from low spreading clumps to tree-sized plants over 10 feet
Care & growing
- Light: Full sun for best growth, flowering, and fruiting
- Water: Very drought-tolerant; water infrequently and let soil dry completely
- Soil: Sandy, gravelly, sharply draining soil
- Temperature: Heat-loving; many species tolerate frost, though ficus-indica prefers mild climates
- Feeding: Minimal; occasional light feeding boosts fruit production
- Propagation: Extremely easy; let a detached pad callus for a few days, then plant it
Habitat & origin
The genus Opuntia is native to the Americas, from Canada through the United States, Mexico, and into South America. Opuntia ficus-indica is believed to originate in Mexico.
Prickly pears grow in deserts, scrublands, and dry grasslands. They have been spread by humans worldwide and have naturalized, sometimes invasively, across the Mediterranean, Africa, and Australia.
Uses & benefits
An important food crop: the young pads (nopales) are eaten as a vegetable, and the fruit (tunas) is eaten fresh or made into juice, jam, candy, and drinks, especially in Mexican cuisine.
Medicinally, prickly pear is studied for blood-sugar and cholesterol effects. It is also used for living fences, livestock fodder, cochineal dye production, erosion control, and as a drought-tolerant ornamental.
Frequently asked questions
Are prickly pears edible?
Yes. Both the de-spined pads (nopales) and the fruit (tunas) are edible and widely eaten, especially in Mexican cooking.
What are glochids?
They are the tiny, barbed hair-like bristles clustered at the areoles. They detach easily and lodge painfully in skin, so handle pads with thick gloves.
How do I propagate prickly pear?
Remove a pad, let the cut end callus over for several days, then set it upright in dry, sandy soil. It roots readily.
Can it survive cold winters?
Many Opuntia species are surprisingly cold-hardy and survive freezing temperatures, though the cultivated Opuntia ficus-indica prefers mild, frost-free climates.
