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.
