About plant names...
Engelmann’s prickly pear is native to North American deserts, at elevations between 1000-4500' (304-1371 m).
Identification: 3-10' (91-304 cm) high, in clumps up to 15' (4.6 m) wide. Thick
pads are oval or rounded. Flowers are yellow to red. Fruit is barrel-shaped, with very short spines
or no spines. Spines are chalky white, sometimes yellow. I couldn’t find any significant differences
between this species and the variety called Tuna Cactus. See this Opuntia comparison table.
