Considered to be one of the finest white Siberian Irises, Iris sibirica 'White Swirl' (Siberian Iris) is a clump-forming perennial that stands out in the late spring to early summer garden. It creates a lavish display of ivory-white, rounded, ruffled flowers adorned with a delicate golden flush at the base of each fall. The elegant blossoms rise atop sturdy flower stalks, well above the foliage. After blooming, the grass-like foliage, consisting of sturdy clumps of upright bright-green, narrow and fairly rigid, blade-shaped leaves, is also one of its most attractive garden features. Spectacular when planted in groups.
