Description

Balsamorhiza sericea is a taprooted perennial herb growing erect 20 to 40 centimeters (8-16 inches) tall. The leaves are mostly located at the base of the plant. They are vaguely fern-like, with each leaf being composed of many pairs of oppositely-arranged lobes. Each lobe is oval and coated in silvery hairs.[3]

The inflorescence bears a single flower head with a center of yellow disc florets and a fringe of yellow ray florets each 2 or 3 centimeters long. The fruit is an achene just over half a centimeter long.[4]
