The scientific name for the common sunflower is Helianthus annuus. This species is native to the Americas and is widely cultivated for its large, showy flowers and edible seeds. Sunflowers are notable for their unique ability to track the movement of the sun across the sky, a phenomenon known as heliotropism, especially during their early growth stage. Sunflower seeds are popular snacks and are used for producing sunflower oil, which is favored for cooking due to its light flavor and high smoke point. Additionally, sunflowers are valued for their ornamental qualities and are often used in gardens and floral arrangements.
