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.

So named for it's extensive use as posts in fencing projects. Another big use is as a fuel in Texas BBQ.
Tree has a fairly extensive range from south central Illinois and very south Iowa down to central Texas and east from Connecticut to Florida.
Leaf has been described as in the shape (roughly) of a Maltese cross.
