The sunflower

The sunflower has a tall and thick stem crowned by what seems like a single giant flower. Interestingly, this flower is no flower at all but a constellation made up of hundreds of small flowers called the head. Although the sunflower head resembles a huge flower with yellow petals and a brown centre, it is actually the brown that is the constellation of flowers, with the yellow leaves acting more as a protectant to the flowers during the flowering and seed development phases. A sunflower can grow to become well over 10 feet (3 meters) tall and the head can become quite wide.
