Iris virginica var. shrevei (Southern Blue Flag) is a rhizomatous perennial forming clumps of sword-shaped, mostly erect, bluish green leaves, up to 3 ft. long (90 cm), with a slight, graceful curve. Tall flowering stalks, unbranched or sparingly branched, rise from the clump in late spring to early summer, each of them boasting 1-2 violet-blue flowers, 3 in. across (7 cm). The falls feature a conspicuously veined white basal patch and a yellow blotch. Blooming for about one month, the pleasantly fragrant blossoms give way to fat green pods, about 2 in. long (5 cm). Very handsome, Southern Blue Flag is a central landscape plant for the water garden, near ponds and streams. This aquatic plant is also a lovely addition to moist borders.
