.
Common name: northern blue flag
Family: Iridaceae (iris family)
Distribution: n.e. and n.-c. North America
IUCN Red list: Least concern
Life form: Herbaceous perennial
Comments: This a clump-forming iris is native to marshes, swamps, wet meadows, ditches and shorelines. It is a marginal aquatic plant that forms a clump of narrow, sword-shaped, blue-green leaves (to 24" long and 1" wide). Flowering stalks rise from the clump to 30" tall in late spring, with each stalk producing 3-5 bluish-purple flowers with bold purple veining. Falls have a central yellow blotch surrounded by a white zone. Clumps spread slowly by tough, creeping rhizomes. This iris thrives in wetland habitats frequented by rushes and sedges.
