Brickellia grandiflora is a species of flowering plant in the daisy family known by the common name tasselflower brickellbush.^[2] It is widespread across much of western and central North America, found in western Canada (Alberta, British Columbia), northern Mexico (Baja California, Sonora, Chihuahua, Coahuila, Nuevo León, Tamaulipas) and the western and central United States (primarily the Rocky Mountains and regions west of there, with additional populations in the central Great Plains (Nebraska, Kansas, Oklahoma) and the Ozarks (Missouri, Arkansas).^[3][4][5][6]
