Yellow Wingstem is a Midwest native perennial plant. The central stem is strongly winged, with scattered white hairs between the ridges. The long leaves are coarse-looking, with a rough texture. Yellow Wingstem blooms with numerous daisy-like composite flowers with a ragged appearance from late summer to early fall. Blooming lasts about 1-1½ months. Sometimes the flowers have a mild fragrance.

Yellow Wingstem flowers are visited primarily by long-tongued bees, especially bumblebees. Some short-tongued bees, butterflies, and skippers also visit the flowers; the long tubes of the disk florets make the nectar inaccessible to many insects with shorter tongues, such as flies and wasps. The caterpillars of the butterfly Chlosyne nycteis (Silvery Checkerspot) and Basilodes pepita (Gold Moth) feed on the foliage. Because of the bitterness of the leaves, Wingstem isn't consumed by deer, rabbits, and other herbivores to the same extent as many other plants. Animals may distribute the seeds to some extent.
