Description en: Genus of about 35 species of solitary or clump-forming, stemless, perennial succulents from arid areas of South Africa. They are grown for their unusual form and attractive flowers. Most have 1 or 2, occasionally 3 pairs of often unequal, erect, very fleshy, greyish or yellowish green or brown to red leaves, often with variably coloured dots; they are usually flattened on the upper surfaces, keeled, rounded, or rounded and partly keeled beneath, and united at the bases. The daisy-like, diurnal, yellow or orange flowers, which sometimes have a coconut-like fragrance, open in late summer and early autumn. In areas where temperatures drop below 7°C (45°F), grow as houseplants or in a temperate greenhouse. In warm, dry climates, grow in a raised bed or succulent border.

Hardiness en: Frost tender.
