The native Nodding Bur-Marigold is common in our area. It prefers full or partial sun, wet conditions, and mucky soil. Habitats include swamps, bogs, seeps, marshes and edges of rivers and ponds. This annual is ½–3' tall and branching sparingly. Its opposite leaves are up to 5" long and 1" across, narrowly lance-shaped and finely toothed. At the base, the pairs of opposite leaves clasp the stem and nearly surround it. The upper stems terminate in flowers ½–1½" across that have a tendency to nod downward with age. Each flower has numerous yellow disk florets surrounded by 8 bright yellow ray florets.
