About plant names...

Ferocactus means “wild or fierce” cactus, and cylindraceus means cylindrical. These cacti are well protected with fishhook-like spines. They are natives of the southwestern United States and northwestern Mexico.

Identification: Plants are up to 9½' (3 m) high and 20" (50 cm) in diameter, usually found singly, rarely branched. The stem has 20-30 ribs which may be vertical or spirally arranged. Most notable are the central spines, of which there are 4-7 in each group. These large spines are variously colored white, red, yellow, or brown. They have rounded or flat cross-sections, and are often curved. Each central spine is 1¾-6" (5-15 cm) long. Radial spines resembling the spokes of a wheel appear underneath the central spine clusters. They are much smaller, almost hairlike, often white, in clusters of 15-25. Yellow (rarely orange) funnel-shaped flowers are 1½-2" (4-6 cm) in diameter and 1-2" (3-6 cm) long. Rarely, the flowers have a reddish midstripe. Fruits are bright yellow 1-1½" (3-4 cm) × ½-¾" (1.5-2 cm), and leathery.
