Gibbaeums are bizarre succulents that grow hidden amongst pebbles; the entire genus is endemic to the Cape Floristic Region, occurring only in the arid habitats of the Little Karoo and surrounds. Gibbaeums are small succulent plants that grow close to the ground (never higher than 200 mm), they can have short lateral stems and some species form clumps. The leaves occur at the end of branches in pairs, are thick and rounded and are unequal in shape, a feature that makes this genus different from a similar-looking vygie genus Argyroderma which has perfectly equal-sized leaves and occurs in the Knersvlakte.
It is a "winter" grower which is most active from autumn and winter and require adequate water and heading for summer dormancy, but it is easy in cultivation and keeps going over the summer too and don’t need particular care. Soil: It grows best in sandy-gritty soil and requires good drainage as it is prone to root rot. It can grows outdoor in sunny, dry, rock crevices (protection against winter wet is required) It can also be cultivated in alpine house, in poor, drained soil. Fertilization: Feed it once during the growing season with a fertilizer specifically formulated for cactus and succulents (poor in nitrogen), including all micro nutrients and trace elements diluted to ½ the strength recommended on the label. It thrives in poor soils and need a limited supplies of fertilizer to avoid the plants developing excess vegetation, which is easily attacked by fungal diseases. Watering: The Gibbaeums thrive in dry and desert regions and are able to stand extended periods of drought and require careful watering. Water minimally in summer, only when the plant starts shrivelling, water more abundantly when they are growing in the autumn and spring, but let the soil dry between soaking. Requires little water otherwise its epidermis breaks (resulting in unsightly scars). If grown in a container, bottom watering by immersing the container is recommended. It must have very dry atmosphere. Light: It needs a bright sunny or light shade exposure in winter, but keep cool and shaded in summer. Hardiness: It prefer a very bright situation and require a minimum temperature 5°C (But will take a light frost and is hardy down to -7° C for short periods if it is in dry soil). USDA zones 9A – 11. Uses: Container, rock garden. Pests and diseases: It is vulnerable to mealybugs and rarely scale. Propagation: Seed in autumn or (or rarely) cuttings. Take the cutting from a grown-up mother plant. Each cutting must contain one or more heads along with a fraction of root and permit to dry out a couple of days, lay it on the soil and insert the stem end partially into the soil. Try to keep the cutting somewhat upright so that the roots are able to grow downward.
