New York Ironweed
New York Ironweed (Vernonia noveboracensis) is a native perennial found throughout the Ridge and Valley, especially in wet meadows, floodplains, streambanks and moist woodland openings. Its brilliant clusters of deep purple flowers bloom from late summer into fall, providing nectar for native bees, butterflies and other pollinators, including migrating Monarchs. Its tall, sturdy stems can reach eight feet, making it one of the most striking wildflowers in a native meadow!
Planting & Care
Plant in full sun to partial shade with medium to wet soil. New York Ironweed thrives in moist meadows, rain gardens and areas with heavy clay soils that retain moisture. Water regularly while establishing and avoid prolonged drought. It grows in sturdy clumps but can spread by seed when conditions are favorable. Give it plenty of space, or cut stems back in late spring to encourage shorter, bushier growth. Leave the seedheads standing through winter for wildlife!
