Golden section in nature

The golden ratio is found all throughout art, design and architecture but it can also be found in naure.

The Fibonacci sequence, 1,1,2,3,5,8,13,21,34,55,89, is foung in flower petals. The number of petals the have is very often from the Fibonacci sequence, for example a lily has petals in threes, a butter cup has 5 and a daisy has 34. Phi also appears in flowers as each petal is placed at 0.618034 per turn (out of a 360° circle) allowing for the best possible exposure to sunlight.

The seeds in a flower head also follow the Fibonacci process spiraling out from the center. To fill the space phi is used to optomise filling.
