An interesting specimen cactus which works well in containers or larger planters that accent it. Interesting when lighted from below at night. It can also be planted in cactus and rock gardens in warmer areas.

Take cuttings of healthy shoots in spring and summer by cutting the stem with a sterile knife just above a bud or shoot. Leave the cutting in a warm dry place until a callus forms over the wound. Once callused, the cutting should be potted up with cactus potting mix topped with a surface layer of coarse grit in which to place the cut end. This prevents the cut end from becoming too wet and allows the roots to penetrate the rich compost underneath in about 2 to 3 weeks.

Requires excellent drainage to prevent rot.

A slow growing, but undemanding ornamental pole-shaped cactus. The obesa or monstrose form is much sought after by collectors and more compact than the Mykleyanus form. It has irregularly-shaped green stems with odd-shaped tubercules and few areoles. Individual stems branch mostly at the base, but occasionally higher along the mostly vertical stems as well. Young stems have a waxy bloom on their surface, but can become very marked with age. Mature stems reach 6 inches in diameter. This naturally occurring hybrid rarely, if ever, flowers and is sterile. It occurs in a limited range in Baja California, Mexico where it reproduces by stem dispersal due to wind breakage and floods. It prefers rich porous soil and can survive drought once a large colony of stems is established. It will tolerate temperatures slightly below freezing if the growing tips are protected.
