Why did moss grow on the north side of trees?
Here in Santa Barbara, California, the sun is not directly overhead, but to the south, so the south side of any object will get more sunlight than the north. This is why moss likes the north side of trees. The fuzzy texture and shade-loving characteristics of moss are in part due to it being a non-vascular plant.
Do lichens only grow on the north side of trees?
Growth on Trees In the northern hemisphere, lichen grows primarily on the north side of the tree, but not completely. Because direct sunlight does not hit the north side of the tree, the bark rarely dries out. This creates an environment where lichen can thrive. Usually, lichen grows around the entire tree.

Types. Spanish moss is a type of epiphyte, a plant that lives on another.
