Iris sibirica 'Caesar's Brother' (Siberian Iris) is a clump-forming perennial with stunning, deep, velvety violet flowers from late spring to early summer. Introducing drama in the garden, each sturdy flower stalk produces many dainty blossoms, well above the foliage of upright, grassy, swordlike leaves. After blooming, the grass-like foliage remains fresh-looking and attractive all season. Spectacular when planted in groups, this lovely Siberian Iris adds drama and vertical interest to the landscape.
