Discover the allure of Bidens cernua, commonly known as Nodding Bur Marigold, an exquisite fall-blooming annual that captivates with its striking beauty and ecological significance. Naturally thriving in damp locations like marshes and seasonal floodplains, this sunflower-relative excels in challenging environments, making it an ideal addition to rain gardens and urban stormwater bioswales. Not only does it thrive without pristine conditions, but it also provides an essential habitat for wildlife. Its bright yellow blooms, measuring 1 to 2 inches across with unique pointed or notched petals, capture the eye from late summer into cooler months. As its name suggests, the flowers nod gracefully as they age, giving way to seeds that ingeniously hitch rides on animal fur and clothing for dispersal. Standing up to 3 feet tall with narrow, toothed leaves that may display a purple hue in partial shade, this plant is a favorite of bees, butterflies, and ducks. Embrace its resilience and charm in your next landscaping project.
