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.

    1st order from Lilyblooms

    Posted by Chris Holland on May 12th 2020

    Arrived yesterday in great shape, over 12" tall with a flower bud. Also, rest of order (red LA Iris, spider Lily, and double flowered Arrowhead) was in good shape and wet. Arrowhead had a mass of long roots - a couple damaged, but there's plenty more - and one dead leaf, which I cut off. As we have a cool cloudy break in our warm summer start, all these plants are now in my pond - I'd attach a photo if I could!
