Mystery of laventa

This tree is super cool because it looks like a hybrid mutant tree! The bottom bark near the ground is tough and gnarly and brown, but then the rest of the trunk and branches have soft white bark like a birch tree. The leaves all have one side that is dark green and one side that is bright white. This makes the tree shimmer like silver everytime a breeze passes by. And finally, to top off the weirdness, it has different shaped leaves! Some are just pointy like a triangle, and others look much more like maple leaves. It's all very confusing!
