Tree leaf Identification
Post oak, Quercus stellata, is a small tree in the white oak group, typically 30–50' tall with 12–24" trunk diameter, tending to grow in the open on poor sites. Low, diffuse branching pattern gives a rugged appearance. Leathery leaves have a distinctive shape, with three perpendicular terminal lobes & tomentose (densely short-hairy) beneath. Acorns are 0.5–0.75". Not good for lumber but hard, tough & rot-resistant wood is great for fence posts & even BBQ wood. Found statewide. #Arkansas

Stout branches grow at right angles to the trunk, forming a narrow round-topped head. Grows rapidly & is tolerant of many soils & varied situations. Leaves alternate, 7-9 lobed, 5-10" long, 4-6" broad; lobes tapering gradually from broad bases & less deeply cut than most others in the red oak group. Acorns mature in 18 mo. Occurs in the northern 2/3 of Arkansas.
