Adding Pale birch trees to the Pale Garden

Have you ever seen birch trees in real life? They often have black spots that resemble the shape of an eye, this happens because of an effect in the human mind called paraedolia, so I think it would be a great opportunity to use this effect to add Pale birch trees.

During the day they look normal, but at night its when those eye shaped spots come to life when they light up and give the effect that birch trees actually have yellow/orange eyes, just like the eye-blossom flowers.
