Cotyledon is a genus of 10 species of perennial shrubby leaf and stem succulents with numerous varieties and cultivars. Mostly from Southern Africa, they also occur throughout the drier parts of Africa as far north as the Arabian peninsula.
This particular cotyledon is growing in a succulent sampler pot only 4 inches deep.
Members of the genus are shrublets, generally succulent, with fleshily woody, brittle stems and persistent succulent leaves. The leaves are opposite. Leaf pairs generally are oriented at 90 degrees to their preceding and following pairs, as is common in the family Crassulaceae
Cotyledons generally colonise rocky ground and cliff faces, a clue that they appreciate well-drained conditions in cultivation.
