Flowers: The flowers are small but colorful, showy. Variable in color and banding usually black or dark-maroon, but also dark-purple, dark green-brown or green. Flowers have a particular scent vaguely remembering of citrus.

Cultivation and propagation: It’s a summer-growing species that like many of the plants of this family which comes from Arabia and East Africa is not easy to cultivate. This plant is extremely adapted to very dry soils and is quite susceptible to over-watering if kept in a non-ventilated place.

Growth rate: Relatively fast-growing that offsets freely to form small clusters quickly.


Exposure: Keep in part to full shade. It has a good heat tolerance.

Watering: Water during the growing period and let dry out when it is dormant. Mature individuals easily rot and die especially after transplanting so be extremely cautious with watering. Keep dry in winter or when night temperatures remain below 10° C. Water it less than average if in bigger pots.

Hardiness: It will not tolerate low temperatures (recommended minimum winter temperature 5° to 10° C)
