A Wetland Wildflower Pictured here blooming in September, Bearded Beggartick (Bidens aristosa) is an annual re-seeding wetland wildflower that occurs on Pocosin Lakes and Alligator River National Wildlife Refuges. It grows to a height of 3 feet and blooms very late in the growing season. The flowers provide pollen and nectar for bees and butterflies. It matures into seed that is high quality food for waterfowl. The refuges moist soil management units are managed to encourage the re-seeding of bearded beggarticks.
