 But to create this elm, what he did was cut one sapling a little bit high off the ground, the other sapling right at ground level, pulled it up by its roots, flipped it completely upside down, trunk to trunk. So the canopy of this tree is actually roots. But due to photosynthesis, it grows leaves. So when you look up underneath the tree, you can see all the gnarly twisted branches that would actually be in the ground if it was the true roots of the tree.
