This sub-shrub is a succulent member of the genus Pelargotetragonum nium. In its native habitat in South Africa it reaches a height of 70 cm (28 in) but, when cultivated as a house plant, it is usually cut back to keep it shorter and to promote branching. The interesting, succulenthave three or four angles, are pale green and glabrous. The five-lobed are heart-shaped at the base and irregularly toothed on the margin. They drop at the end of the growing period. The sparse inflorescence usually consists of only two or three long-stalked , which are coloured pink and have prominent violet blotches. There is a marked difference in the size of the petals: the two upper petals are much bigger than the three lower ones.
During the growing period provide plenty of light (it tolerates direct sun), warmth and water. In winter, restrict, provide light and cooler conditions, about 15°C (59° F).
