Iris hellenica is a plant species in the genus Iris and the subgenus Iris. It is a rhizomatous perennial, from Saitas Mountain, in the Peloponnese Region of Greece. It has grey-green, sickle-shaped leaves, a tall slender stem, 2–3 white, lavender-blue, lilac or purple flowers and orange/purple beards. It was thought once to be a hybrid species of Iris germanica which also grows in the same area, before being separated into 2 species. It has only recently been published and is rarely cultivated as an ornamental plant in temperate regions.
