Devil's Beggarticks (Bidens frondosa) is found throughout North America and occupies a variety of damp habitats, including bogs, lakeshores, streambanks, and wet meadows. It is particularly adapted to sunny shorelines.
Devil's Beggarticks typically bloom from late summer into fall, often from July to October. During this time, the plant produces an abundance of small, dirty-yellow composite flowers that are clustered at the top of the stems. Although demure and rather uninteresting flowers, the long blooming season provides a valuable food source for late-season pollinators such as bees and butterflies. Mature plants have large, serrate leaves that are perhaps more striking than the flowers, giving it an elegant and unique appearance. Devil's Beggarticks may also serve as a host plant for the caterpillars of some butterfly species. The plant's seeds are equipped with barbs that allow them to adhere to passing animals, aiding in seed dispersal.
While not recommended for manicured gardens due to its potential to be aggressive, Devil's Beggarticks can be used in restoration for providing additional cover and wildlife resources in damp areas. It can tolerate a range of soil types, including clay, loam, sandy, and peat soils. Surface sow in spring and keep the soil consistently moist until germination occurs, which usually takes around one to two weeks.
