Discovery: Native to the Americas. Since the 16th century, sunflowers have been an important food source and oil crop. Only recently, sunflowers have also become a popular cut flower. Immature flower buds do exhibit phototropism - directional growth of the plant in response to sunlight - however mature flowers generally face the East and do not move.
