Cultivation:  This cactus is cultivated and highly priced for its flowers.   It is among the easiest species to grow, flower and propagate.  Water regularly from March to October.  Rot prone in winter, it needs good drainage.  Claret Cups require strong sunlight to maintain a healthy appearance, and a harsh "dry and cool" winter environment combined with maximum light exposure enhances spring flower production.  Frost Tolerance: Hardy to -5° C.
Propagation:
Seeds (usually), it also can be grown from cuttings, as it branches profusely from the base.
