Iris versicolor

Iris veriscolor, commonly called Blue Flag, is a clump-forming iris that grows in marshes, swamps, and ditches. Forms a clump of narrow, arching-to-erect, sword-shaped, blue-green leaves. Flowering stalks rise from the clump to 30” tall in late spring, with each stalk producing 3-5 bluish-purple flowers. Rhizome is poisonous so use gloves when handling.
