Tree tunnels are perfect examples of how nature can be shaped over many years by humans and other external influences. When paths and roads are carved into the ground, nearby trees bend outward into the new patch of light to receive more energy for photosynthesis. This process continues until the tree branches on either side completely overlap, forming a thick ceiling over the pathway beneath.
In the case of the more flowery passageways like the Wisteria Tunnel (above) found at the Kawachi Fuji Gardens in Kitakyushu, Japan, gardeners strategically place the easily trained, hanging flowers along a curved trellis.
