This species is one of those plants that is lost in the grand rearrangement of the cactus family. Some call it an Echinocereus, some refer to it as a cultivar. All we know is that it is a scrambling cactus with round, ribbed stems and numerous white spines. The flowers are large, white, and open at night. It is frost hardy in Tucson, having withstood multiple frosts of 15F. These plants are rooted cuttings in 4-inch pots.
