The African Milk Barrel is a succulent that is grown for its colour and is planted in arid or succulent gardens as a specimen or in containers for indoor or outdoor use. It establishes from division in 2 to 4 years and is long lived. It may be difficult to obtain from nurseries and care should be taken when handling as the sap is poisonous and corrosive. ID 1828
