Quercus Acutissima Japanese Silkworm Oak ‘Sawtooth Oak’ (Caliper: 3-3.5″)

Quercus acutissima, commonly called sawtooth oak, is a medium sized deciduous oak that is included in a section called the “Cerris” group, which has traits that are somewhat intermediate between the red and white oak sections. It typically grows 40-60’ tall with a broad-spreading, rounded crown. Gray to black bark develops corky ridging with age. It is native to China, Korea and Japan. Insignificant monoecious yellowish-green flowers in separate male and female catkins appear in spring as the leaves emerge. Fruits are oval acorns (to 1” long), with spiny, scaly cups that extend to approximately 2/3 the acorn length. Acorn crops can be quite abundant and are an important source of food for wildlife. Oblong to lance-shaped, chestnut-like, glossy dark green leaves (to 7” long) have bristle-tipped marginal teeth at the terminal point of each parallel vein. Fall color is variable, ranging from an attractive golden brown to undistinguished pale brown.
