Adromischus, belonging to the Crassulaceae family, is a South African endemic genus, of small clumping species. Several of these species are quite popular and can be found pretty easily in the cactus and succulent section of most nurseries and garden centres. Their leaves are their fascination: oddly shaped, interestingly marked, and endlessly variable. They have small, upright flowers, generally white to pink to lavender, with fused petals. Most species of Adromischus are propagated easily by seeds or leaf cuttings. Adromischus require a well-drained soil mixture and a dry atmosphere. They grow best in part shade. Water mostly in spring and autumn and let them dry out between watering. Keep drier in winter and water early in the day during summer. They are prone to mealy bug attacks, which can be controlled with a soapy solution sprayed directly onto the plants and washed of an hour later with clean water. Adromischus species are frost hardy to -7°C. Adromischus are well suited to pot culture or being grown on windowsills and do well in raised garden beds and rockeries.

Adromischus cooperi, synonymously known as Adromischus cooperi var. immaculata, Adromischus cuneatus, Adromischus festivus, Adromischus halesowensis, Adromischus pachylophus, Cotyledon cooperi and Cotyledon cooperi var. immaculata and commonly known as Bontplakkie, is distributed in the Eastern Karoo between Somerset East, Graaff-Reinet, Middelburg and Queenstown. This slow growing succulent is a small plant with very thick, green to greyish green succulent leaves, which are beautifully mottled on the upper surface with large purple markings. The leaves taper to both ends and have an acute white horny margin. The flowers, albeit insignificant, are pinkish in colour. Adromischus cooperi is cold hardy to -10°C if kept dry. During active growth, water regularly.
