0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 and so on. Each number is obtained from the sum of the two before it. These numbers are important in nature.
The head of a sunflower is made up of small seeds, which are produced at the center. They migrate towards the outside to fill all the space. Each seed is angled in relation to the one before it. The angle of the seeds to each other is 137.5 degrees. With this angle, the optimal filling up of seeds with the same spacing occurs.
The number of petals is often one of these numbers.
We were also given a few sunflower seeds to plant at home.
