Blue Flag Water Iris

(Iris versicolor) and Yellow Water Iris (Iris pseudacorus) are ornamental perennials that grow along shorelines. The sword-like leaves arise in late March to early April and grow 1-2 feet tall. Blue flag iris offers showy violet flowers that bloom during May to July. Yellow iris produces showy yellow flowers that bloom in July. Water iris is supported by a robust root network that provides excellent shoreline stabilization. Iris also offers important shoreline habitat for an array of wildlife.
