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!!
