The plant is widespread across much of western North America, found in western Canada (Alberta, British Columbia); northern Mexico (Baja California, Sonora, Chihuahua, Coahuila, Nuevo León, Tamaulipas); and the western and midwestern United States (primarily the Rocky Mountains and regions west through California, Oregon and Washington, with additional populations in New Mexico and Texas, and the central Great Plains (Nebraska, Kansas, Oklahoma) and the Ozarks (Missouri, Arkansas).[3][4][5][6]

Description

Brickellia grandiflora is an upright perennial herb growing a few-branched stem up to 70 centimeters tall. The hairy, glandular leaves are up to 12 centimeters long and lance-shaped, triangular, or heart-shaped.[6]

The inflorescences at the tip of the slender stem holds clusters of nodding flower heads, each just over a centimeter long and lined with greenish phyllaries with curling tips. The bell-shaped flower head holds a spreading array of 20 to 40 disc florets. The fruit is a hairy cylindrical achene about 4 millimeters long with a pappus of bristles.[6] The bloom period is July to September.

The rust fungus Puccinia subdecora grows on Brickellia grandiflora.[7]
