Cultivation:
It’s a fairly easy species to cultivate.  It needs a very well-drained soil, and requires strong sun to part sun to keep the plant compact and low and to develop a good spinal growth. Waterings should be rather infrequent to keep the plant compact, and avoid its becoming excessively elongated and unnatural in appearance. Furthermore it has a tap root, and watering it properly is often difficult, because it tends to crack open or rot if over-watered. Keep dry in winter, or when night temperatures remain below 10° C.  It is hardy to -4°C for a short period.  Assure a good ventilation.

Reproduction: From seed, since the plant rarely produces plantlets, or occasionally grafted.
