The kooky Spiral Cactus begins its life as a straight cactus, the ridges beginning to spiral once it reaches a height of approximately 10cm. In nature it usually grows as a shrub with numerous columns in a candelabra-like arrangement. Cereus forbesii 'Spiralis' is a trunkless cactus that forms numerous tall, columnar, blue-green, spiral stems branching at the base in a candelabra-like arrangement. Stems have a waxy blossom on the surface, reach a height of 6-13 feet and are 4-5 inches in diameter. The stems have five to nine widely spaced ribs. Spiraled Cereus is a heavy bloomer. Large purple fruits are easily produced when blossoms are pollinated. It is not poisonous. The spines are sharp so the plant should be handled carefully. Synonyms include Cereus peruvianus forma spirale, Cereus peruvianous tortuosus, Twisted Cereus, and Contorted Cereus.
