Helianthus argophyllus
Also called Silver Leaf Sunflower
Silverleaf sunflower is a native annual sunflower of coastal Texas with silvery, hairy leaves and stems, growing up to about 3 m tall. It thrives in full sun and sandy, well-drained soil.
Helianthus argophyllus is a North American species of sunflower known by the common name silverleaf sunflower. It is native to the coastal regions of the US state of Texas, and naturalized in other places (Florida, North Carolina, Argentina, Africa, Australia, etc.).
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.
