Helianthus cusickii is a species of sunflower known by the common names Cusick's sunflower and turniproot sunflower. It is native to the western United States from Washington, Oregon, Idaho, northern California, and northwestern Nevada.[1][2][3]
Helianthus cusickii grows in mountain forests and foothills. This wildflower is a perennial up to 120 cm (4 feet) tall, growing from a thick, fleshy taproot. The lance-shaped leaves reach 15 centimeters (6 inches) in length, and the stem and foliage are often covered in long hairs. The flower heads have a base of long, hairy green phyllaries. The center of the head is filled with at least 40 yellow disc florets surrounded by 12–16 ray florets.[4]
Some Plateau Indian tribes used the roots to treat erectile dysfunction, wasting, and tuberculosis. [5]
