more fibonacci..

..and this time the spiral on this gorgeous bush of Isopogon wildflowers.

This evening the lad and I had a delightful wildflower walk with J and her girls (lad and lassses are dogs needless to say!).
The bush is blooming with flowers and blushing with colour including orchids but the Isopogon caught my eye.
Isopogon is a genus of 35 species endemic to Australia, 27 of which are found here in the West.

They display the ' "fibonacci spirals" (two intersecting spiral lines - one shallow one, and the other much steeper) which allow for the plant head to grow without rupturing open along a single weak line'.
