Iris versicolor, Blue flag iris, is a hardy lakeshore herbacious perennial typically found in the shallow waters of pond edges, sedge meadows, marshes, along stream banks and in forested moist soil wetlands. Blue flag iris forms sword-like foliage 2-3' tall growing from thick creeping rhizomes. The elegant flowers of Blue flag iris are 2-4" across and usually light to deep blue and bloom from May to July.
