I saw this plant in its native South Africa sprawling across baking rocks and growing in barely any soil.  Despite (or, perhaps, because of) its inhospitable site it was smothered in flowers.  Back in Britain we found the plant in that treasure house of rare and unusual plants, Cally Gardens.  It has glaucous, fleshy leaves that resemble a succulent, and in cultivation its stems are less woody than in the wild although it is just as floriferous.  It will start flowering in May and would continue through the winter if I didn’t cut it back in October to give it a rest.  Needs the protection of a cold greenhouse during the winter.

Propagate from cuttings or collect a few seeds and sow them in the spring.  There is a lot of variation in the colour of the pink flowers on plants grown from seed.

I also grow a variegated form, with white and green leaves.  Attractive but not as vigorous as the species.
