These Totem Pole cactus are so crazy-looking! especially en masse. Totem Pole Cactus, Pachycereus schottii var. monstrosus.

The totem pole is a spineless, bumpy cactus that developed as a natural mutation from the senita cactus. It grows naturally only in a small area of Baja California. All the totem pole cacti in a population are a single clone; it rarely flowers and cannot produce fertile seeds. It can reproduce by “pupping” from roots, and you can grow new plants simply by placing a cut branch in soil. They are often used as landscaping plants. Some horticulturists warn not to touch the cactus with bare hands because skin oils will damage the cactus.

Both senitas and totem pole cactus share the genus and species name Lophocoreus schottii (aka Pachycereus schottii). A subspecies name of monstrosus is added to the totem pole cactus in some classifications. Or Lophocereus schottii f. monstrosus
