What is a common pattern in the nature?

There are many patterns in the nature. Maybe everything in the nature would have theirs own pattern.
However the interesting is that there is no straight line. Every shape and pattern has a curve.
Moreover we can see that usually the curve and pattern are repeated.

In advance, I put together many kinds of patterns, and arrange that by regular order. And then,
try to draw a line as the pattern. I found many patterns and finally I thought that
flower is one of the things which have patterns overall, and from among flowers, roses also have
an inclusive pattern.
