Vernonia novaboracensis (New York ironweed)

University of Maryland Extension Recommended Native Plant

New York ironweed, a tall, clump-forming perennial, is an absolute favorite for rain gardens. Growing up to 6', it produces showy deep purple flowers in August and September. Plant in full sun in medium to wet soils. It will self-seed if allowed. If you prefer a shorter plant, you can cut it back in late Spring. The dried seeds are lovely accents in the garden throughout the winter.

New York ironweed is native to the eastern U.S. In Maryland, it is locally common across the state in open wet areas. New York ironweed is the most common species of Maryland's four Vernonia species. The flowers attract butterflies, and the seedheads attract birds. Also has special value as an attractor of native bees. Host plant for various moth species.
