Iris prismatica

Blue Iris

Similar to the Iris versicolor except for the narrower leaves, this hardy lakeshore perennial herb is typically found in the shallow water such as edges of ponds, sedge meadows, marshes, along stream banks and in forested moist soil wetlands. Blue Iris forms narrow sword-like foliage less than 1/2" wide reaching 1-2' tall growing from thick creeping rhizomes. The elegant flowers 2-4" across are usually light to deep blue and bloom from May to July.
