It prefers an open sunny position, and grows in moderately fertile very well drained sandy stony-soils and is drought and frost tolerant.

Old-man cactus is grown for its hairy appearance and clumping habit.  It is commonly grown as a potted house plant or used in rockeries and arid settings. It is suitable to mountainous regions and establishes in 3-5 years and is moderately long lived. In cold climates it is grown under glass in cactus collections, requiring a bright sunny dry position.
