Glottiphyllum depressum

Glottiphyllum is a genus of about 57 species of succulent subtropical plants of the family Aizoaceae.

The name comes from the ancient Greek "γλωττίς" (glottis=tongue) and "φύλλον" (phyllos=leave).

The species are native to South Africa, specifically to Cape Province and the Karoo desert. They grow in rocks and soils incorporating slate, sandstone and quartz. Rainfall in their native areas is between 125 and 500 mm, especially in March and November.

Description

The plants have thick, soft leaves arranged in pairs, which are low to the ground, often grazing the soil surface. They have rhizomes. They sport yellow flowers with narrow petals, sometimes fragrant, around five cm diameter, which appear in autumn and winter. The species readily interbreed; hybridization is easy.

Culture

Glottiphyllum plants can be grown in small pots in poor soil with sand and clay. They require very sunny exposure, and need moderate watering in summer and not at all in winter (during which the plant undergoes a necessary rest period). If overwatered, the plants become deformed.
