The genus Moraea belongs to the Iridaceae family and is a close relative of the genus Iris. It is accepted that it evolved independently from Iris itself, which is restricted to the Northern Hemisphere. Therefore, it is strictly an African genus extending from Nigeria and southern Ethiopia, into the African highlands down to the southern tip of Africa where winter rainfall is predominant. Many are indigenous to South Africa. It is in the winter rainfall area where one finds the highest concentration of Moraea species. They have long narrow basal leaves, sometimes only one per corm and large yellow, pink, orange, or bicolor flowers with six fairly equal tepals. The genus name is a tribute to the English botanist Robert Moore. Moraeas have iris-like flowers. They make good potted plants and are suitable rockery plants too. Most enjoy well-drained soil and full sun to flower best.

Moraea crispa is a South African endemic species from the Eastern Cape, Free State, Northern Cape and Western Cape Provinces where it can be found growing on clay slopes in Fynbos, Nama Karoo and Succulent Karoo from Cederberg Mountains to Baviaanskloof, southern and western Karoo. It grows to 20cm tall with a single leaf. During spring, in the afternoon, open the tiny blue-mauve flowers with yellow nectar guides.
