"The Chestnut Oak tree, Quercus prinus, is a medium-sized, native, deciduous tree. Chestnut Oak trees are also called Rock Oak, Rock Chestnut Oak, or Mountain Oak. It is long-lived and slow-growing rugged tree. The characteristic bark is dark and very rough. On older trees it typically is broken into long, V-shaped ridges that are separated by deep furrows. Chestnut Oak is amazingly free of major pest and disease problems, a testament to superior genetics in all aspects of its growth cycle."
