Always a popular favorite, Iris sibirica 'Shirley Pope' (Siberian Iris) is a clump-forming perennial with wonderfully dark, velvety flowers in late spring to early summer. Each blossom features large, flared, deep violet-blue petals adorned with a prominent white signal veined with purple at the base of each fall. They open up from large buds, almost as beautiful as the flowers. After blooming, the grass-like foliage, consisting of sturdy clumps of upright blue-green, narrow and fairly rigid, blade-shaped leaves, is also one of its most attractive garden features. Unlike some other varieties, the foliage stands up straight and is not as prone to the stems collapsing and requiring propping. Spectacular when planted in groups.
