Description

Post Oak is a deciduous tree that may grow 40 to 60 feet tall. The tree has alternate leaves with 5 lobes and a hairy, pale underside. The two middle lobes are distinctly square, resulting in an overall cruciform appearance. The bark is scaly in younger trees. As the tree ages, a more blocky and rigid appearance develops. In spring, yellow-green, cylindrical, male flowers and reddish, female spikes mature. The tree produces a 1/2- to 2/3-inch acorn with a warty cap that covers about 1/3 to 1/2 the nut. The acorn requires one growing season to reach maturity.

No pests or diseases of major concern but the tree occasionally succumbs to Chestnut blight and is susceptible to oak wilt.

Fire Risk: This plant has a low flammability rating.
