Iris sibirica ‘Caesar’s Brother’ is an upright vase-shaped plant with long, grass-like leaves. Flower stem extend above this basal foliage in mid-June, each bearing several flowers with prominent lower lips. The flowers are a vivid dark blue, with lighter colored throats. Flowers last only a few days once they open. This plant will not perform well unless it gets plenty of sun. If planted in part shade, very few blooms will form. Over time it will spread to form very dense stands with thick, tough, roots that are challenging to divide. Will also self-seed and come fairly true to form. Deer do not bother this plant.
