About plant names...

The Arizona barrel cactus is native to southwestern North America. Adult plants often lean toward the south, perhaps because strong southern sun inhibits growth on that side, hence the name “compass barrel cactus.” Sometimes the lopsided columns tip over in the mud following a sudden rain.

Identification: Round or column-shaped, plants are usually single, 3-9½' (1-3 m) high and 31" (80 cm) around, with 20-30 ribs. Stems are asparagus-colored. There are two types of spines. Central spines, the largest and most prominent, may be red, white, or gray. They are round or flattened in cross-section, occurring in groups of 4-7. One spine is largest, often shaped like a hook, and 3-4" (8-10 cm) long; smaller spines are straight. Underneath the central spines are radial spines, which are white, much thinner (almost hairlike), and more flush against the stem. Funnel-shaped flowers are 1½-1¾" (4-5 cm) in size, usually orange but grading into red and yellow, blooming from July to September. Oval shaped fruits up to 1¾" (5 cm) are yellow.

Edibility: Ripe fruits are edible, “tart and lemony,” with firm texture. Indigenous Americans also processed the pulp into a cabbage-like food.
