White Oak
(Wide & Flat: Alternate Arrangement)
A dominant forest tree on dry to moist sites throughout the Commonwealth usually reaching 80'-100' high. This tree is very important to both wildlife and people. The acorn is an important wildlife food and eastern Native Americans made a flour from these acorns. Traditional uses of White oak wood include hardwood flooring, whiskey barrels and boat building. The famous Revolutionary War frigate, USS Constitution, "Old Ironsides", was made of White oak. The "white oak group" includes all oaks without bristle-tipped lobes and acorns that ripen in one season.
