It was first published and described by Pierre Edmond Boissier and George François Reuter in 'Pugillus Plantarum Novarum Africae Borealis Hispaniaeque Australis' (Pugill. Pl. Afr. Bor. Hispan.) Vol. 113 in January 1852. It was then illustrated in Curtis's Botanical Magazine, Tab. 6775 on 1 September 1884.

It is native to Africa. It is found in Morocco and Algeria. It is also found in North Africa, Spain and Portugal. It is very susceptible to iris mosaic virus. It can be propagated by bulblets, 1 to 4 small bulbs growing beside the main bulb which can then be taken off and planted to grow on to form a new bulb. It has a reputation of being a difficult species to grow in the UK. Even in the US, it is restricted to be grown in mild climates such as southern California. Due to the limited hardiness of the species, it is better grown in a bulb frame or grown in a dry border then lifted and stored like dahlias. It can be grown in pots for inside or outside displays. Known cultivars include; Iris tingitana 'Paris' (large dark blue violet flowers)
