Northern Wildflowers Ironweed New York Pkg.

Approximately 125 seeds per package, covers 30 ft²
 
New York Ironweed (Vernonia noveboracensis) is found in moist areas in the wild, but will also flourish in a garden with medium soil. Native to the eastern portion of the United States, this species is hardy up to zone 5. The species tolerates clay and acidic conditions well. It attracts butterflies and the seed heads are a food source for birds. New York Ironweed's tall, narrow growth habit makes it ideal for placement in borders or to fill in tight spaces in the garden. The species has a naturally low germination rate, hence, over-seeding is recommended.
