Iris Sibirica 'Super Ego'

Siberian Iris

Iris sibirica ‘Super Ego’ — commonly called Siberian iris — is a vigorous clump-forming perennial known for its rich deep violet-purple flowers with a velvety appearance and subtle lighter markings near the base of the falls, blooming in late spring to early summer above upright, narrow green foliage. Its saturated flower color and strong stems make it especially striking in mixed borders and moist garden plantings.
