Post oak

Fagaceae (Beech family)


A 30- to 60-foot-tall tree in the Beech family, post oak has a few large branches and a rounded crown. It is a perennial, warm-season native with reddish brown bark.

A post oak leaf is dark green, oblong, about 4 to 6 inches long and deeply five-lobed. The rounded middle lobes are located opposite each other, giving the leaf a cross-like appearance. The leaves are hairy underneath.

Post oak provides fair grazing for wildlife but can be poisonous to livestock.


The range of native post oaks extends from Central to East Texas.
