Sawtooth Oak Fact Sheet
Family: Fagaceae - Beech family
Latin name: Quercus acutissima
Common name: Sawtooth oak
- Plant Symbol = QUAC80
- Sawtooth oak (Quercus acutissima) is a good shade tree. It is also a good source of food and cover for wildlife.
Sawtooth oak is native to eastern Asia but was introduced into the eastern United States around 1920.
- LEAVES: The leaves of Sawtooth oak are 4-8 inches long. They have pointed teeth with a bristle at the end of each vein. Sawtooth oak leaves are similar to those of the chestnut but are smaller. Leaves are glossy green in the summer. The leaves turn brown in the winter and may stay on the tree through most of the winter.
- TWIGS: The summer twig shows small acorns and next year's buds in the leaf axils.
- FRUIT: Acorn - about 1" in diameter with a fringed cup. About 2/3 of the nut is covered by the cup. Pictures of acorns taken and August, October and January.
- NOVEMBER BUDS. Are these unusual? Throughout November I watched the buds in one area of this Sawtooth oak and they appeared to be opening as they would in the spring. The leaves have also remained longer than those of any tree in the area!! NOTE*** At some point during the winter the lower branches on the tree were removed, so the buds that I had photographed were gone.
