Quercus Acutissima Sawtooth Oak is a large, deciduous tree with a broad-spreading, open, and rounded crown. Sawtooth Oak is covered in chestnut-like, shiny, bristle-toothed dark green leaves with slightly wavy edges that turn yellow to golden brown in fall. Inconspicuous, yellow-green catkins appear in spring. The blossoms give way to rich brown, oval acorns. The dark gray bark and reddish-brown furrows of this tree add interest to the landscape. This shade tree is ideal for specimen plantings. It grows best in rich, humusy, medium-moisture, well-drained soils under full sunlight.
