Brickellia grandiflora, known by the common name tasselflower brickellbush, is a species of flowering plant in the family Asteraceae.[2]
Description
Brickellia grandiflora is an upright perennial herb growing a few-branched stem up to 70 centimeters (28 inches) tall. The hairy, glandular leaves are up to 12 cm (4 3⁄4 in) long and lance-shaped, triangular, or heart-shaped.[3]
The inflorescences at the tip of the slender stem holds clusters of nodding flower heads, each just over 1 cm 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 (1⁄8 in) long with a pappus of bristles.[3] The bloom period is July to October.[4]
The rust fungus Puccinia subdecora grows on Brickellia grandiflora.[5]
Distribution and habitat
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).[6][7][8][3]
It can be found on forest banks and cliffs at relatively high elevations.[4]
