Golden angle. Artwork showing the angle between repeating spirals in a floral pattern. Each repeating spiral is degrees apart. This angle is known as the 'golden angle' and is mathematically related to the number Phi (). It can be derived from the formula: 360 multiplied by 1 minus the reciprocal of Phi. Phi itself can be calculated from the Fibonaci series of numbers (1,2,3,5,8,13,21 etc) by dividing one Fibonacci number by the preceeding number in the sequence. The pattern of spirals in the middle flower is known as Fermat's Spiral and is commonly found in plants such as on the florets on a sunflower head.
