Bidens cernua, also known as Nodding Beggarsticks, Nodding Bur Marigold, and Sticktight, is a beautiful herbaceous plant native to North America. Growing up to 3 ft tall in wet areas, Bidens cernua boasts sessile leaves with coarsely-toothed margins, and nodding yellow flowers that mature into numerous yellow flower heads. The flower heads are sometimes oriented horizontally or downwards, giving it the Latin name "cernua," which means "nodding." This plant thrives in wet habitats such as swamps, marshes, and flood plains and is widespread across much of Eurasia and North America. While its seeds are sometimes eaten by ducks, Bidens cernua is commonly used medicinally to treat urinary-tract infections. If you're looking for a stunning plant species to add to your garden, Bidens cernua is a great option.
