Astroloba is a genus with around 10 species of herbaceous, succulent perennials native to the Cape Province of South Africa. This genus is closely related to the genus Haworthia, but may be distinguished from it by the flowers. Astroloba have regular flowers that are not double-tipped, as most Haworthia species are. These are arranged in clusters on slim flowering stalks and are coloured green-white, yellow, red or pink. Foliage is fleshy and extremely regular in appearance, sharply triangular and these species produce multiple stems. Older specimens with longer stems tend to fall and grow in a sprawling manner rather than an erect habit as in younger, smaller plants. They are adapted to rocky, dry environments in inland areas in the Southern Cape of South Africa. The process of speciation takes many many years to complete, due to this ongoing process, species in this genus have diverged and differentiated over time. However, if they are located in the same area, they may still interbreed to produce fertile offspring. Thus subgroupings, termed complexes exist within this genus: the Foliolosa complex species are identifiable by possessing glossy foliage.
