This Northern Blueflag Iris is a wild species that grows in swamps, marshes, along pond and water edges from southern Labrador to southern Manitoba through Minnesota & Wisconsin & Illinois to Ohio to Virginia up to Massachusetts. It is the provincial flower of Quebec. This species usually grows about 2 to 2.5 feet high and has 3 to 5 flowers on each stalk blooming in late May to June, even early July in the far north. While it is found only in wet places in the wild, even growing in shallow water 2 to 4 inches deep, it does well in average, mesic garden soil. It can be grown like the cultivated irises. It also has thick rhizome roots from which it spreads slowly. It can be divided and reset after blooming. The word "flag" comes from Middle English meaning a "rush" or "sedge."
