Quercus alba, the white oak, is one of the preeminent hardwoods of eastern and central North America. It is a long-lived oak, native to eastern and central North America and found from Minnesota, Ontario, Quebec, and southern Maine south as far as northern Florida and eastern Texas. Specimens have been documented to be over 450 years old.

Although called a white oak, it is very unusual to find an individual specimen with white bark; the usual colour is a light gray.[ 화이트 오크라고 불리지 만, 흰 껍질을 가진 개별 표본을 찾는 것은 매우 드문 일입니다. 일반적인 색상은 밝은 회색입니다.] The name comes from the colour of the finished wood. In the forest it can reach a magnificent height and in the open it develops into a massive broad-topped tree with large branches striking out at wide angles.

Description

Quercus alba typically reaches heights of 24 to 30 metres (80–100 feet) at maturity, and its canopy can become quite massive as its lower branches are apt to extend far out laterally, parallel to the ground. Trees growing in a forest will become much taller than ones in an open area which develop to be short and massive. The Mingo Oak was the tallest known white oak at over two hundred feet with a trunk height of 44.2 m (145 ft) before it was felled in 1938. It is not unusual for the crown spread of a white oak tree to be as wide as it is tall, but specimens growing at high altitudes may only become small shrubs. The bark is a light ash-gray and peels somewhat from the top, bottom and/or sides. According to Chris Bolgiano in The Appalachian Forest: A Search for Roots and Renewal, the largest tree ever cut in West Virginia was a white oak that measured thirteen feet thick at its base.

White oak may live 200 to 300 years, with some even older specimens known. The Wye Oak in Wye Mills, Maryland was estimated to be over 450 years old when it finally fell in a thunderstorm in 2002.
