   This erect columnar species tends to branch from the base, and can grow rapidly to about 10' tall, or sometimes more.  The ribbed 3" to 8" diameter green stems have straight, stiff, brownish-red spines, that mature to black.  Native to the Sonora Desert in the United States and Mexico, it needs full sun, little to moderate water, and though mature plants may handle some frost, you may want to protect the growing points. In spring and summer this night bloomer produces white, 3" wide flowers, followed by a red, 2" to 3" long, edible fruit that loses its' spines when it ripens.  Propagation is done from the
dark brown seeds of this fruit, or from cuttings.
