Helianthus argophyllus is an annual herb sometimes as much as 300 cm (10 feet) tall. Leaves and stems appear silvery because of a coating of many hairs along the surface. One plant can produce 1-5 flower heads, each 15–20 ray florets surrounding 150 or more disc florets. The plant grows in sandy areas near the seacoast.
