Ironweed can grow to a height of 7 to 10 feet in deep moist soils, but usually averages around 5 feet. The stem of the plant is very hard and stiff, hence the name. Spear shaped leaves around 6 inches long grow all along the length of the stem. The purple flowers bloom from late July to early October and form in clusters at the top of the plant. Ironweed is in the Composite family, meaning the individual purple flowers you see are not the true flowers. Like daisies and asters, the real flowers are a cluster of small tube-like structures that form the “disk” at the center of what looks like a single purple flower.
Though pretty to look at, ironweed is considered a weed to most farmers. In pasture fields it can be an indicator of overgrazing, but is easily controlled with herbicides or clipping. Cattle won’t eat it, and the only wildlife that use it are insects, especially bees and butterflies. For honeybees it is an excellent source of nectar. Native Americans used the root of ironweed as a pain reliever following childbirth, for stomach ailments, and to control bleeding.
