A vigorous, mainly aquatic rhizomatous plant, herbaceous in texture, perennial and evergreen, with very rapid growth and a dense, clump-forming habit: at full size it can exceed 1 m in height, while spreading sideways almost indefinitely, to the point that in some cases it becomes invasive and poses a serious problem for neighbouring species in the same ecosystem. From the sturdy, widely branched underground organ rise numerous fans of narrow, long, ribbon-like leaves, with smooth margins and a pointed tip, leathery and hairless, of a bright green colour. In late spring, loose inflorescences rise above the foliage on fleshy, hollow stems, made up of golden-yellow flowers with the broad corolla typical of the genus Iris: three larger petals, set 120 degrees apart, bend downwards and are veined with purple, while three smaller ones, alternating with the first, rise upwards and then curve over like a hook. If fertilised, in autumn they form elongated capsules full of brownish seeds, which allow the plant to spread readily in the wild.
