The sawtooth oak has very long, tear-shaped, and prominently serrated, glossy dark green leaves. These leaves will turn yellow or golden brown in the fall. The oval brown acorns are topped with interesting, scaly, almost hair like cups that cover ⅔ of the acorn. After about 10 years, the tree’s acorn crop can become very abundant. These acorns are an important food source to wildlife.
