The sunflower (Helianthus annuus) is a flowering plant in the family Asteraceae, with a large flower head (capitulum). The stem of the flower can grow up to 3 metres tall, with a flower head that can be 30 cm wide.
Sunflowers are native to North and South America, and were first domesticated by the Native Americans thousands of years ago. Today, sunflowers are grown all over the world as a food crop, ornamental plant, and for their oil.
Sunflowers are heliotropic, meaning that they turn their heads to follow the sun throughout the day. This helps the flowers to absorb more sunlight and produce more seeds.
Sunflowers are an important source of food and oil. Sunflower seeds are edible and can be eaten raw, roasted, or salted. They can also be used to make sunflower butter, sunflower oil, and other food products. Sunflower oil is a healthy cooking oil that is high in monounsaturated fats and low in saturated fats.
Sunflowers are also a popular ornamental plant. They are often grown in gardens and parks for their bright yellow flowers. Sunflowers are also a popular choice for cut flowers.
In addition to their food and ornamental value, sunflowers are also used in a variety of other products, such as biodiesel fuel, lubricants, and cosmetics.
