The Post Oak, sometimes called the iron oak or rough oak, is native to the eastern and central regions of the United States. It is fairly low maintenance and capable of growing in various types of soils. The second part of the Latin name, stellata, means “star”, which is most likely a reference to the shape that is formed by the lobes. Our post oak is one of the oldest tree specimens remaining on the South 40. It was recently saved from creeping vines which were strangling the tree, the remnants of which can still be observed on the tree today.
