Geraea canescens is also known as the desert sunflower, hairy desert sunflower, or desert gold. It is a dicot and annual of the Aster (Asteraceae) family. "Geraea" in its scientific name comes from the Greek geraios ("old man"), referring to the white hairs on the fruits.^[1]

The desert sunflower has a yellow sunflower-like flower, each flower on a slender, hairy stem. It grows 1-3 feet (0.3–1 m) high. The leaves are gray-green and grow to 3 inches (7.6 cm) long. It flowers February through May after sufficient rainfall.

It is native to western North America, specifically Arizona, Nevada, California, and Utah. A drought-avoiding annual plant, it can be found in the California, Mojave, and Sonoran Deserts. It grows from sea level to 4,265 feet (1,300 m) in sandy desert soil in the company of creosote brush.^[2]

The flowers attract bees and birds. Seeds are eaten by birds and rodents.^[3]
