Towering, thick-stemmed, large-leaved plant crowned by sunflower-like yellow-orange flowers. The opposite leaves are connected to each other around the stem, forming a small cup that collects water and attracts birds. Tolerates clay soil. Goldfinches love eating the seeds in the fall. The Xerces Society recommends this species as "highly attractive to pollinators" in the Great Lakes region.
