Trees are one of the most quintessential fractals in nature. As they grow, branches develop from the trunks, and each of these branches is like a smaller tree in itself, developing its own branches and their own branches. If you look at a complex tree, you will notice the repetition of the Y shape throughout.
This kind of fractal design, like the spiraling of succulents, helps trees optimize their exposure to sunshine and prevents top branches from shading out lower ones.
