Ericameria gilmanii is a shrub growing up to 50 centimeters (20 inches) tall.[5] The foliage is aromatic.[2] The leaves are up to 1.2 centimeters (0.5 inches) long, curved backward, and glandular and resinous. The inflorescence is generally a single flower head, or sometimes more than one. The head has a bell-shaped base with curving phyllaries which are green to tan. The head contains a few white ray florets and has white disc florets at the center. The fruit is a hairy achene which is roughly a centimeter long including its pappus.[5]

Ericameria gilmanii grows in forests. The one known population is on United States Forest Service land. Other occurrences presumed to still exist are also on federal land.[4]
