Sunflowers have either 34, 55 or 89 petals on their face, depending upon the size of the sunflower. This number is based from the Fibonacci number and flower patterns. Fibonacci numbers are based on a certain sequence.
The number of spirals in the center of a sunflower corresponds to a specific Fibonacci number. The head of the sunflower is made up of small seeds that are produced at its center and then migrate towards the outside of the flower.
