Iris graminea, common name Grass-Leaved Flag, is a herbaceous perennial plant belonging to the genus Iris of the Iridaceae family. The specific epithet graminea, meaning grassy in Latin, refers to the grass-like cluster of leaves.
Iris graminea reaches on average 20–50 centimetres (7.9–19.7 in) of height. These plants have spikes bearing two flowers about 8 cm in width, almost hidden by grass like narrow leaves 5–15 millimetres (0.20–0.59 in) wide and 35–70 centimetres (14–28 in) long. The flowers have a plum scented fragrance and the color varies from purple to violet blue. The falls of the flowers are usually violet, while the hafts are yellow, white and purple veined. The flowering period extends from April through June.
This species is native to Central and Southern Europe, with a distribution ranging from Germany, Spain, France and Northern Italy to the Caucasus.
These plants prefer thermophilous deciduous woods, on the edge of forest clearings and shady paths or on the banks of a stream. They can be found at an altitude of 0–1,000 metres (0–3,281 ft) above sea level.
