Sunflower

The sunflower (Helianthus annuus) is an annual plant native to North America and an important crop used in many parts of the world. Its large yellow flower heads consist of hundreds of small, tightly arranged florets that open in the morning and close at night. Sunflowers are an important source of food for animals, providing nectar and pollen for bees, as well as seeds for birds. They are also cultivated for their oil, which is often used for culinary and cosmetic purposes. Sunflowers are also popular ornamental plants, grown in gardens for their cheerful and sunny appearance.
