Cultivation and Propagation: A draining cactus potting mix and a good water supply is all this plant needs, it like full sun to light shade with warm temperatures. It tends to lose its leave and go dormant in winter. It then needs very little water. Repot the plant every 2-3 years.
Crested growth: Unlike 'monstrose' varieties of plants, where the variation from normal growth is due to genetic mutation, crested growth can occur on normal plants. Sometimes it's due to variances in light intensity, or damage, but generally the causes are unknown. A crested plant may have some areas growing normally, and a cresting plant that looks like a brain, may revert to normal growth for no apparent reason. Any normal shoots should be removed to promote the growth of the crest.
