Vernonia noveboracensis is a very adaptable wildflower. It is just as happy in average garden soil as it is in soggy pond edge soil. It tolerates drought and partially sunny spots. A great plant for the back of the border as it is quite tall but it is not very wide. The color of the flower is absolutely gorgeous! The seed heads turn a lovely rusty brown color. Self sows readily in the garden. Makes a great 'thriller' (center plant) in a planter and a nice fresh cut flower.
Fun Fact: Native Americans used New York Ironweed as a pain reliever.
Maintenance: Cut back to the ground in late spring to control height and to have a more floriferous plant.
