Product Overview
Blue Flag Iris (Iris versicolor)
Blue Flag Iris is a small to medium iris with narrow green foliage growing to about 24-30". The attractive spring flowers are violet blue. An excellent choice for naturalizing along stream beds, natural pond shorelines, and marshy areas. Native to the NE United States, Blue Flag Iris is very easy to grow, winters over easily and performs well in any size water garden. This species is sometimes referred to as Northern Blue Flag Iris, to distinguish it from Southern Blue Flag Iris.
