Fun Facts

Nodding beggarticks is found in wetlands, marshes, pond edges, and wet disturbed areas. It produces bright yellow, daisy-like flowers in late summer and fall. The flower heads often bend downward after blooming, giving the plant its common name. It prefers full sun and consistently moist soils and is especially useful in rain gardens, wet meadows, and shoreline plantings. It is excellent for naturalized wet areas. You may want to allow it to self-seed to have plants from year to year. It does not perform well in dry garden beds.
