Plant Description

Wild Blue Flag used to be a familiar sight in northern boggy areas, but increasing development has restricted its habitats. Given damp or at least moisture retentive soils, this iris will produce vigorous clumps of arching leaves 2 feet tall. Clusters of 2- to 3-inch purplish-blue flowers rise several inches above the foliage in early summer. They variously may have yellow blotches on the signals or purple veining on the falls. Reportedly, the flowers do well as fresh cuts. Blue Flag is a wonderful plant for sunny, damp areas where it combines well with Cardinal Flower, Turtlehead, Clethra, Obedient Plant, Gentians, and Hibiscus.
