The Post oak is native to Arkansas, and can make a great landscape tree when given plenty of room as evident at UA Fort Smith. The stand of Post Oaks located along Grand Avenue and Waldron are considered to be the oldest grouping of trees on campus. This grove of trees appear to be remnants of the original postoak-blackjack oak forest that would have predominated this area some 100 to 150 years ago.

Bark: The bark of the Post Oak is a grayish color and often fissured into scaly ridges.

Foliage: The 4 to 8 inches long and 3 to 4 inches wide leaves of Post Oak trees are usually dark green and shiny on the upper surface and lighter green and rough hairy beneath, with a thick, leathery feel. Each leaf has two to three lobes with the middle pair being much larger than the others. The leaves turn to a golden color in the fall.

Flowers: There are both yellow-green male and female flowers on the tree, but the male flowers drop catkins. The flowers bloom from late March to April.

Fruit: An acorn that can be up to 3/4 to 1 inch long and about 1/3 to 1/2 of it is enclosed by the cap.
