Spirals are often seen in nature. It’s surprisingly common for these spirals to be a visual representation of a series of numbers, such as the Fibonacci series. In the Fibonacci series, each number in the series is the sum of the two previous numbers.

However, I haven’t often seen this kind of spiral in a rose. So I was delighted to be able to photograph this one in the wind and sunshine of our front porch!
