Description edit
Balsamorhiza macrolepis is a taprooted perennial herb growing erect 20 to 60 centimeters tall. The large lobed leaves are lance-shaped to oval and the largest, generally toward the base of the plant, may approach 50 centimeters (20 inches) in length. They are bright to dull grayish-green and coated in fine hairs.[2]
The inflorescence bears a single flower head lined with hairy, glandular phyllaries up to 4 centimeters long. The head has a center of yellowish disc florets and a fringe of pointed yellow ray florets each 2 or 3 centimeters long.[5]
