Estimated Native Range
Summary
Vernonia noveboracensis, commonly known as New York Ironweed, is a deciduous perennial herb that is native to moist meadows, floodplains, and wetlands of the Eastern United States, from Massachusetts to Florida and west to Ohio. It typically grows to a height of 7 feet (2.1 meters) and a width of 3-4 feet (0.9-1.2 meters), with a clumping form. New York Ironweed is characterized by its tall, upright stems and deep purple flowers that bloom in late summer, which are highly attractive to butterflies and other pollinators. The flowers are quite showy, making it a popular choice for naturalistic plantings and pollinator gardens.
This species is valued for its tall, striking flower heads, which add vertical interest to garden borders and wildflower meadows. It is also used for streambank stabilization due to its tolerance of wet conditions. In cultivation, New York Ironweed thrives in full sun to part shade and prefers consistently moist, rich soils with good drainage. It is relatively low-maintenance once established but may require staking in very rich soils to prevent flopping. While it can spread by seeds and rhizomes, it is not typically aggressive in garden settings. However, in ideal wetland conditions, it can become more assertive.CC BY-SA 4.0
