The common sunflower (Helianthus annuus) is a large annual forb of the genus Helianthus. First domesticated in the Americas, sunflower is cultivated across the world for its oil and fruits. Sunflower seeds (the edible fruit) are typically produced and sold as a snack food for human consumption, bird feed, or as livestock forage. Sunflower oil (extracted from the seeds) is commonly used in cooking, but it is also utilized as a biofuel in the emerging biodiesel market. Additionally, sunflowers are cultivated for the production of latex and nonallergenic rubber.
