Sunflower (Helianthus annuus) is an annual plant native to the America. Its name is derived from the flower’s shape and image, which is often used to depict the sun. The plan raises its flower in the morning, follows the sun on the sky, and goes to sleep at sunset. The plant has a rough, hairy stem, broad, coarsely toothed, rough leaves and circular heads of flowers. The heads consist of many individual flowers which mature into seeds. From the America, sunflower seeds were brought to Europe in the 16th century, where, along with sunflower oil, they became a widespread cooking ingredient.
