The Golden Ratio

Back to Fibonacci!

Plants turn in spirals as they grow, so that the cells are not produced in straight lines. It is better to grow in a circlular motion, because this is sturdier and more compact. The golden ratio for plant rotation is 1.61803... which is demonstrated in the leaf roations or flower patterns below:

When two successive Fibonacci numbers are divided, they equal numbers close to the golden ratio!

2 / 3= 1.5

3 / 5 = 1.666666

5/ 8 = 1.6
