They are native to the temperate zones of the Northern Hemisphere and found in diverse habitats ranging from arid, semi-desert areas, colder montane regions, meadows and marshes. Leaves are narrow and strap-like and fan-shaped, symmetrical flowers are borne on erect stems. Irises are widely cultivated and many varieties and hybrids are available bred for their attractive showy flowers in diverse often intense colours.
