    Post Oak is a handsome large tree that is native to almost all of the South, plus eastern Kansas, all Missouri, southern Illinois & Indiana & Ohio, and New Jersey and southeast Pennsylvania. It has unique-shaped, glossy, thick, leathery leaves that turn golden brown in autumn. It grows on upland sites, slopes. hills, and mountains. It grows about 3/4 foot/year and lives 300 to 400 years. It develops a taproot, so it is hard to transplant. It is offered by a few native plant nurseries.
