Narrow Leaf Ironweed

Vernonia angustifolia

Also known as Slender Ironweed, Narrow-leaved Ironweed

Narrowleaf ironweed sends up slender, wand-like stems crowned with rich magenta flowerheads throughout the peak heat of late summer. Adapted to the fire-maintained pine savannas and sandy flatwoods of the southeastern Coastal Plain, its extensive root system allows it to resprout readily following surface burns. The disc florets produce copious amounts of nectar, providing a vital late-season food station for monarch butterflies, swallowtails, and native bees.
