VERNONIA fasciculata (Prairie Ironweed)
Smooth ironweed is the common name for Vernonia fasciculata, which has glabrous leaves, stems, and flower heads. Despite its resilience, the plant is a very unexceptional ornamental, with the exception of its attractive flowers. Butterflies are attracted to flowers. This ironweed plant has a proclivity for hybridizing with other native ironweeds.
