Quercus austrina, the bastard white oak or bluff oak, is an oak species that is endemic to the southeastern United States from Mississippi to the Carolinas, with a few isolated populations in Arkansas. Quercus austrina can grow to a height of 45 to 60 feet (13.5-18.0 meters) with a spread of 35 to 50 feet (10.5-15.0 meters). Leaves are narrow, with shallow rounded lobes. It tends to grow in wet habitats, such as on river bluffs, river bottoms, and flatwoods, and generally over basic substrates, such as mafic rocks, shells, or calcareous sediment.
Bluff Oak is a native, deciduous oak tree found along the southeast USA from North Carolina south into Florida and west into Mississippi. It naturally occurs on well-drained, rich bottomland soils along streams and on river bluffs. It is becoming endangered in some areas.
It is small for an oak tree and the open rounded crown makes it a great shade tree. The fall colors are showy and the numerous acorns are loved by wildlife.
