Iris Sibirica 'Silver Edge'
Siberian Iris
Iris sibirica ‘Silver Edge’ — commonly called Siberian iris — is an elegant clump-forming perennial distinguished by soft lavender-blue flowers edged with a fine silvery-white margin, blooming in late spring to early summer above slender upright green foliage. The subtle contrasting edge gives each bloom a refined appearance, while the narrow foliage adds graceful vertical texture through the growing season.
