Cereiform glaucous succulent stems with profuse black blossoms from early spring to late summer.  An easy-to-grow species in this interesting genus.
 

Cultivation:  Water normally in the growing season, sparsely in the winter.
It is usually recommended to over-winter them in warm conditions (at 10° C), but despite their African origins they seem to grow well and flower without the extra heat which one might have thought necessary, and occasional temperatures near 0°C.  are tolerated, if kept dry. 
Spring:   In the spring  leaving them out in the rain may provide them with the water they need.
Summer:  In the summer months they will grow well in partial shade and tolerate heavy rain, but will be just as happy if the season is dry.
Propagation:  Easiest with stem cuttings.  Allow cuttings to dry several days before planting.
Potting medium:   Since roots are quite shallow, use a cactus mix, or add extra perlite or pumice to regular soil potting soil.
A gritty, very free-draining compost is suitable, and clay pots help the plants to dry out between watering.
Sun Exposure: full sun or partial shade.
