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 overwinter them in warm conditions (at 10° C) but despite their African originsthey 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.
