Blue Flag    Iris versicolor

This two-to-three-foot-tall plant is a natural along a water’s edge where its small, slender violet-blue flowers bloom in early summer. Its thick rhizome roots are land stabilizers. The rhizomes should be planted just below the soil in full sun or partial shade – but they should be handled with care (and gloves) because sap in the roots can cause dermatitis.
