Sunflowers are usually tall annual or perennial plants that in some species can grow to a height of 300 cm (120 in) or more. The disk of a sunflower is made up of many little flowers. Sunflower oil is a valued and healthy vegetable oil and sunflower seeds are enjoyed as a healthy, tasty snack and nutritious ingredient to many foods. While the vibrant, strong sunflower is recognized worldwide for its beauty, it is also an important source of food. Sunflower seeds are high in protein and rich in healthy fats, as well as antioxidants that can lower your risk of developing serious conditions.
