Winged Loosestrife (Lythrum alatum)

    Winged loosestrife is a wetland perennial plant native to the eastern half of the United States and Canada. It likes to grow along marshes, lakes, ponds, ditches, wet prairies, and swales. During the first few years of its life, it is only a few feet tall, but as these pictures indicate, winged loosestrife can get pretty tall, as tall as 6 feet in later years.
