Vernonia noveboracensis

New York Ironweed
Vernonia noveboracensis
Vernonia noveboracensis

This variety is right at home in a meadow; long blooming clusters of violet-purple flowers sway in the breeze from late summer until fall; great for borders or massed as an accent; very undemanding and drought tolerant

Ornamental Features

New York Ironweed has masses of beautiful clusters of purple flowers with violet overtones at the ends of the stems from late summer to mid fall, which are most effective when planted in groupings. Its serrated narrow leaves remain green in color with pointy creamy white spines throughout the season.

Planting & Growing

New York Ironweed will grow to be about 4 feet tall at maturity extending to 6 feet tall with the flowers, with a spread of 4 feet. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 3 feet apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 10 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!
