Cultivation:
It’s a fairly easy species to cultivate, but is quite prone to rot, especially after the first flowering. Needs a very well-drained soil. Will benefit from adding up to 30% Gypsum to the potting mix.
Requires strong sun to part sun. Waterings should be rather infrequent to keep the plant compact, and avoid it becoming excessively elongated and unnatural in appearance.
During the winter rest period they should be dry and cool. Interrupt watering when night temperatures remain below 10° C.  It is hardy to -4°C for a short period.
Assure good ventilation.

Propagation: Seeds.
