Vernonia Fasciculata Seeds - Flower Plant

Vernonia fasciculata, commonly known as Common Ironweed, is a hardy native perennial prized for its dense clusters of vivid purple flowers and sturdy upright stems. It is an excellent choice for pollinator gardens, prairie restorations, wildflower meadows, rain gardens, and naturalized landscapes. The plant thrives in full sun with moist to moderately well-drained soil and blooms from mid-summer through early fall.
