It is native to the Mojave Desert and Sonoran Desert in the southwestern United States, in California, Nevada, and Arizona.[2]Brickellia incana is a shrub growing in a spherical clump on the sandy desert floor, 40 centimeters to 1 meter tall. The leaves are gray-green to white with a thin coat of woolly fibers, oval in shape and up to 3 centimeters long.[3] The inflorescences hold solitary flower heads, each about 2.4 centimeters long and lined with woolly gray-green to grayish purple phyllaries. Each flower head holds an array of about 60 red, yellowish, or grayish disc florets. The fruit is a hairy cylindrical achene about a centimeter long with a pappus of bristles.[3] References1. ^The Plant List, Brickellia incana A.Gray 2. ^Biota of North America Program 2014 county distribution map 3. ^1 Flora of North America, Brickellia incana A.
