Iris virginica var. shrevei
Common name: Blue Flag Iris
Blue Flag Iris is a fast growing, water-loving species. Showy purple flowers with yellow streaks bloom from late spring to early summer. Although each individual flower is short lived, a colony can bloom for as long as a month. Because they are so fast growing, they benefit from divisions every 3-4 years. If left alone, this plant frequently forms colonies, particularly in wet areas. Although they can grow in part shade, they often will only bloom under full sun conditions.
