About Quercus austrina Small
Quercus austrina Small, commonly called bastard white oak or bluff oak, is an oak species. It is endemic to the southeastern United States, ranging from Mississippi to the Carolinas, with a small number of isolated populations located in Arkansas. This species can reach a height of 45 to 60 feet (13.5–18 meters), with a crown spread of 35 to 50 feet (10.5–15 meters). Its leaves are narrow and feature shallow rounded lobes. It typically grows in wet habitats including river bluffs, river bottoms, and flatwoods, and usually grows over basic substrates such as mafic rocks, shells, or calcareous sediment.

It also requires full sun exposure and has high drought tolerance.
