In 1941, Maryland designated the White Oak, (Fagaceae Quercus alba,) as its state tree (Chapter 731, Acts of 1941; Code State Government Article, sec. 13-310).
Handsome and sturdy, the white oak is named for its whitish bark and grey twigs. White Oaks are large, long-lived, and slow-growing trees, reaching heights of 60 to 150 feet, with diameters between 3 to 4 feet. Their glossy, bright green leaves have rounded lobes, five to seven per leaf. The species is found commonly throughout Maryland. The most famous example of the White Oak was the Wye Oak at Wye Mills, Maryland.
White oak (Quercus alba) is an outstanding tree among all trees and is widespread across eastern North America. The most important lumber tree of the white oak group, growth is good on all but the driest shallow soils. Its high-grade wood is useful for many things, an important one being staves for barrels, hence the name stave oak. The acorns are an important food for many kinds of wildlife.
The law designating the white oak as the official Maryland state tree is found in the Maryland Statutes, Title 13, Section 13-310.
