Summary
New York ironweed is a robust wildflower with saturated-violet and narrow petaled flowers. Clusters of finely petaled flowers, in dense clusters, top a 5-7’ clump-forming plant. Normally found in nature in wet swales, Vernonia novaboracensis also grows well in drier sites in the garden without extra care. The intense purple flowers bloom for most of the month of September and attract many butterflies. Grow New York ironweed in full sun to filtered shade. It grows well in the flower border or native meadow garden with Andropogon virginicus, Helianthus angustifolius, Conoclinium coelestinum, Symphyotrichum novae-angliae, Liatris spicata, and Helianthus microcephalus.
