Iris missouriensis
Blue Flag
Iris missouriensis can be found in wet spots throughout the region. A relative of the common Irises used in the landscape trade, Iris missouriensis has showy flowers that appear in the late spring. The plants spread by rhizomes, and also produce seed pods that follow the flowers. The erect, dried seed pods are a good way to locate these plants in the winter months. Like most blue/purple flowers, white versions are possible.
