About
Opuntia macrorhiza, also known as the prairie pricklypear, western pricklypear, twistpine pricklypear, or plains pricklypear (a name more commonly given to Opuntia polyacantha), is a common, widespread species of cactus native to North America.
Where it grows
The species prefers well-drained, sandy or gravelly soils, mostly in grassland areas. It grows at elevations of 600–2,400 m (2,000–7,900 ft). It is found throughout the Great Plains of the United States, from Texas to Minnesota, and west into the Rocky Mountain states to New Mexico, Utah, and perhaps Idaho, with sporadic populations in the Mississippi and Ohio Valleys. It is also reported from northern Mexico in the states of Chihuahua, Sonora, Coahuila, Nuevo León, Durango, Tamaulipas, and San Luís Potosí., though all Arizona and Mexican records should be considered with caution due to confusion with other similar species. The species is cultivated as an ornamental in other locations.
