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]
