Late summer wildflowers are coming on strong across Iowa. During the past three weeks, I’ve seen the first flowers of 2017 on brown-eyed Susan, common evening primrose, goldenrod, ironweed, cutleaf coneflower, common sneezeweed, white snakeroot, yellow jewelweed, and even New England aster, which usually appears later and continues to produce flowers until the first frost.
Today’s featured plant is nearing the end of its blooming period for the year. Winged loosestrife (Lythrum alatum) can be found in a variety of wet habitats, such as “moist black soil prairies, marshes, fens, borders of lakes and ponds, areas along rivers and drainage ditches, and low-lying ground along railroads.” Sometimes called winged lythrum, this species is native to most of North America from the Rocky Mountains to the east coast.
I took all of the enclosed photos between late June and late July on lower ground in the prairie restoration area along the Windsor Heights trail, behind the Iowa Department of Natural Resources building on Hickman Road.
Note: winged loosestrife can be confused with purple loosestrife (Lythrum salicaria), which is “now ranked among the most highly problematic invasive species in North America.” At the end of this post I’ve included two pictures of purple loosestrife. If this attractive plant is growing on your property, I recommend pulling it up.
