In this picture, the crabapples are growing in groups of two, three, five, and eight. These are all fibonacci numbers. This tree, like many others, seems to grow fruit and foliage in groups of fibonacci numbers. Additionally, the smaller of these numbers can all be added to amount to the larger numbers. That is, a group of two and a group of three can make up and group of five, or a group of three and a group of five makes a group of eight. This relates to the golden ratio.
