Gull's Wing Siberian Iris, Siberian Iris

Iris sibirica ‘Gull’s Wing’ — commonly called Siberian iris — is an elegant clump-forming perennial noted for its pure white flowers with subtle yellow markings at the base of the falls, blooming in late spring to early summer above slender upright blue-green foliage. The clean white blooms create a bright, graceful effect in borders and moist garden settings, while the fine-textured foliage remains attractive throughout the season.
