Upper left: this tiny oxeye daisy was growing in our yard when I photographed it a couple of summers ago. I noticed the seedhead pattern, so I enlarged it (next right). That pattern is of a series of spirals, both clockwise and counterclockwise. Those spirals are described by a Fibonacci number sequence, e.g. 1-2-3-5-8-13 (next right). I then enhanced the pattern (next right) using the Topaz Simplify filter and Photoshop. Finally, I did a wide crop through the enhanced seed head pattern (bottom image).
It turns out that oxeye daisies and sunflowers and many other flowers have structures that follow the Fibonacci sequence. This arrangement maximizes the number of seeds that can be packed into a seedhead. Even the branching of leaves on a wildflower stalk can follow the Fibonacci sequence, for similar reasons. Google it.
Who would have thought all this is embedded in the DNA of an oxeye daisy?
