This species, considered by some to be a Stenocactus, is from Coahuila, Chihuahua, and Durango, Mexico, generally east of the Sierra Madre. What makes this species interesting are the wavy ridges to the flutes in the body, which make it look more like a green filter than a plant. The flowers are white and not the reason one obtains this plant. We offer seedlings in 4-inch pots.
