Description
This is a perennial herb which can take the form of a prostrate creeper along the ground to a somewhat erect shrub approaching 0.5 m (1.6 ft) in height. The stem and foliage are fleshy, with the leaves thick and oval or spade-shaped. The plentiful inflorescences are curled, coiling double rows of small bell-shaped flowers. Each flower is white with five rounded lobes and a purple or yellow throat. The fruit is a smooth nutlet.
