Attractive glaucous blue-green barrel cactus with yellow flowers and spines. Sharp, well-defined ribs are armed with spines that are not easily distinguished as central or radial. May be solitary or clumping. From Hidalgo, Mexico.

Flowers around 6 inches wide, not including spines. May be self fertile. Grown from seed. Enjoys a little extra space in containers, compared to many Ferocacti. Can grow to 18 inches high and 20 inches in diameter after many years. Provide strong light and excellent drainage in cultivation.
