Iris is a genus of 260300 species of flowering plants with showy flowers. It takes its name from the Greek word for a rainbow, referring to the wide variety of flower colors found among the many species. As well as being the scientific name, iris is also very widely used as a common name for all Iris species, though some plants called thus belong to other closely related genera. A common name for some species is 'flags', while the plants of the subgenus Scorpiris are widely known as 'junos', particularly in horticulture. It is a popular garden flower. The genera Belamcanda (blackberry lily), Hermodactylus (snake's head iris), Neomarica (walking iris) and Pardanthopsis are sometimes included in Iris. The genus is widely distributed throughout the north temperate zone. Their habitats are varied, ranging from cold and montane regions to the grassy slopes, meadowlands and riverbanks of the northern hemisphere.
