Description

• Opuntia is a genus of cacti in the family Cactaceae, commonly known as prickly pears or paddle cacti. Most species have flattened, jointed stem segments called cladodes, which carry out photosynthesis and store water. These segments bear clusters of small, barbed bristles called glochids, often accompanied by larger spines. The showy flowers are typically yellow, orange, pink, or red, and develop into fleshy fruits that may be green, yellow, orange, red, or purple when ripe. Many species are adapted to dry conditions and are important sources of food and shelter for wildlife.

Range

• The genus Opuntia is native to the Americas, ranging from Canada and the United States through Mexico, Central America, the Caribbean, and South America. Mexico is a major centre of diversity for the genus. Several species occur naturally in Zihuatanejo, Guerrero, and the surrounding area.

Habitat

• Species of Opuntia grow in a wide variety of habitats, including deserts, tropical dry forests, coastal scrub, grasslands, rocky slopes, and disturbed ground. Most favour sunny locations and well-drained soils, with many tolerating prolonged drought and intense heat. Some species also grow in coastal environments or seasonally moist tropical habitats. Their flowers provide resources for pollinators, while their fruits are eaten by birds, mammals, and other wildlife.
