Quercus bicolor, commonly called swamp white oak, is a medium sized, deciduous tree with a broad, rounded crown and a short trunk which typically grows at a moderate rate to a height of 50-60' (sometimes larger). Leaves are dark, shiny green above and silvery white beneath, with 5-10 rounded lobes along the margins. Fall color is yellow, but sometimes reddish purple. Insignificant flowers in separate male and female catkins in spring. Fruits are acorns which mature in early fall. Grows in moist to swampy locations in bottomlands and lowlands, such as along streams and lakes, valleys, floodplains and at the edge of swamps. Also has surprisingly good drought resistance.
The specific epithet refers to the leaves being shiny green above and silvery white beneath.
This is a durable and long-lived tree, but is susceptible to some insect galls, caterpillars, borers, leaf miners, and oak lace bug. Chlorosis (yellowing of the leaves while the veins remain green) can occur when soils are not properly acidic. Can be difficult to transplant and establish, so it's best to plant from containerized stock when the plant is small (5' or less).
It's a fast growing oak, ideal for use as a specimen tree, street tree, or shade tree. A great tree for wet ground and low spots.
