Noted for its distinct upright habit and striking flowers, Iris versicolor (Blue Flag) is a rhizomatous perennial forming a clump of narrow, upright or gracefully recurving, sword-shaped, blue-green leaves. Branched stems rise from the clump in late spring to early summer, each of them boasting 3-5 bluish-purple flowers, 4 in. across (10 cm), adorned with bold purple veining. The falls feature a conspicuously veined white basal patch and a yellow blotch. Very handsome in and out of bloom, Iris versicolor is a central landscape plant for the water garden, near ponds and streams. This marginal aquatic plant is also a lovely addition to moist borders.
