Sunflowers are bright, cheerful flowers known for their large, round heads and vibrant yellow petals. They are named for their ability to turn towards the sun, a behavior called heliotropism. Sunflowers can grow quite tall, sometimes reaching heights of over six feet. Their seeds are not only tasty but also nutritious, making them a popular snack and ingredient in many dishes. In addition to their beauty, sunflowers play an important role in nature. They attract bees and other pollinators, helping to support local ecosystems. The seeds can also be harvested to produce sunflower oil, a common cooking oil that is low in saturated fat and high in healthy fats.
