The crested forms are cultivated for their beautiful stem with dense bristly spine and pronounced sculpture effects. These plants produce monstrous crests, and crests occasionally produce normal shoots. Flowers are produced only on the the apex of normal stems. Crested specimens are often grafted on stronger species, called the stock, that can be any number of different columnar cactus.
