Trees are, in fact, fractal from their seeds to their roots to their leaves to their canopy. If you look closely at the veins of the leaves, you'll notice just how self-similar they are. The tiniest ones look like the main midrib (the midline vein), and the midrib looks like the tree trunk with its branches.

This is true only of reticulate venation (weblike, not parallel, veins).
