New York Ironweed
Vernonia noveboracensis

A bold native perennial known for its tall stems and vibrant clusters of deep purple flowers that bloom in late summer. The rich color and upright form make this species a standout in meadows, wet prairies, and rain gardens. Its strong stems rarely require staking and add dramatic height and structure to native plant communities.
