“There are three main ways to identify an aspen tree.
The first is by its leaves. Aspen leaves are small and oval-shaped with sharply pointed tips. They are also arranged in pairs on the stem, unlike most other trees which have leaves that alternate along the stem.
The second way to identify an aspen tree is by its bark.
Aspen bark is very smooth and white, often with a greenish tinge. It is also very thin, so you can often see the tree’s inner layer of bark through the outer layer.
The third way to identify an aspen tree is by its branches.
Aspens have very slender branches that are often curved or drooping. The ends of the branches are also often covered in small buds.”
