Food AdditivesHelianthus annuus is an annual species of sunflower grown as a crop for its edible oil and edible fruits (sunflower seeds). This species of sunflower is also used as bird food, as livestock forage (as a meal or a silage plant), and in some industrial applications.
The plant was first domesticated in the Americas. Wild Helianthus annuus is a widely branched annual plant with many flower heads. The domestic sunflower, however, possesses a single large inflorescence (flower head) atop an unbranched stem.
