The leaves occasionally succumb to powdery mildew during the fall. This plant is less tolerant of dry conditions than other Bidens species. Cut back plants in late winter. This fairly aggressive species is a good choice for wetland restorations. Attracts bees, butterflies and birds. Food source for caterpillars.
