Discover the majestic Vernonia gigantea, commonly known as Giant Ironweed or Tall Ironweed, a striking perennial from the Asteraceae family. Native to the eastern United States and parts of Canada, this resilient species thrives in diverse environments, from New York to Ontario and southwest to Texas. This impressive plant reaches heights of 3 to 7 feet, showcasing robust stems that can take on a green or purplish hue, with either a smooth or hairy texture. Its dark green leaves, up to 10 inches long, feature a range of shapes from ovate to lanceolate-oblong, with serrated edges and a smooth upper surface.

From July to September, Tall Ironweed bursts into vibrant bloom, presenting clusters of radiant purple flowers that attract pollinators and add a vivid touch to meadows and open woodlands. Perfect for moist soils, it thrives by roadsides and open environments. With seeds dispersed by wind and substantial ecotypic variation, Vernonia gigantea ensures a broad geographic distribution. Add this hardy beauty to your landscape for a dynamic display of color and resilience that signifies the essence of wild American flora.
