Nodding-beggarticks is an annual wildflower in the Aster family native to North America and Eurasia. It can be found on shores, wetlands, and waters edge under full sun to part shade. Leaves are coarsely toothed and lance-shaped, arranged in opposite pairs. Large showy flower heads resembling sunflowers bloom from August to October. They turn downward as they mature, hence the name cernua, meaning "nodding". Ducks sometimes eat the seeds and the flowers are especially attractive to native bees!
