Iris sibirica 'Ruffled Velvet'

Ruffled Velvet Iris

Iris sibirica ‘Ruffled Velvet’ — commonly called Siberian iris — is a vigorous clump-forming perennial noted for its rich deep violet-purple flowers with softly ruffled petals, blooming in late spring to early summer above slender upright blue-green foliage. The saturated flower color and lightly ruffled form give it a bold yet elegant appearance in perennial borders and moist garden settings.
