The large blue flag iris (Iris versicolor) —also known as Harlequin Blueflag, Large Blue Iris, Northern Blue Flag— is a perennial in the Iridaceae (iris) family native to Canada and the United States, spanning south from Nova Scotia into the middle and northeastern United States to Virginia. The specific epithet, 'versicolor,' is derived from this plant's ability to produce many-colored blooms while the common name, 'flag,' comes from an old English word (flagge) for reeds and refers to its natural preference to wetlands. In fact, it prefers to grow in rich, moist soils and thrives in full sun.

The sword shaped blue-green clumping leaves reach 2 to 2½ feet tall topped with a mass of blue lavender to white blooms. The blooms are formed of three upright inner standards and three distinctly marked sepals. The leaves are narrow and strap-like 1 inch wide and up to 24 inches long crossing at the base to be fan-like.
