Ironweed

Vernonia fasciculata

Information provided by Prairie Nursery

“Named for its tough stem, ironweed has excellent posture and never slouches in the garden. The attractive floral display is a torch-shaped cluster of deep violet flowers, held aloft on a single, tall unbranched stem. This native perennial is a favorite for adding late season color to the landscape. Ironweed tolerates clay soils very well. It prefers a moist environment but does just as well in a medium garden soil. Excellent in a prairie/wildflower garden, tall border, naturalized drainage area or raingarden. Ironweed is a host plant for the American Painted Lady butterfly.
