Cactus Apple or Engelmann Pricklypear is a common Prickly Pear in the southwestern United States. It has beautiful showy large yellow flowers and blooms across its range from April to July. Opuntia engelmannii Cactus Apple spines are evenly distributed on pad or absent, white to yellow, aging gray to blackish, spines are straight to curbed; the glochids widely spaced, yellow to red-brown also aging gray or blackish. Opuntia engelmannii Cactus Apple has striking fruits, often called “Tunas” of deep red or magenta. The fruits are mostly without spines and very juicy (bleeding and staining). The Tunas are eagerly used for fruit, food and other purposes by southwestern United States indigenous peoples. Opuntia engelmannii The Acoma Pueblo peoples of New Mexico enjoy the fruits or Tunas of Cactus Apple in a variety of ways.
