Connecticut State Tree: White Oak
Fact-checked • Updated January 15, 2025
Connecticut State Tree – White Oak
Connecticut made official the White Oak (Quercus alba) as its state tree on April 16, 1947. Governor James L. McConaughy signed the legislation after advocacy from the Connecticut Tree Protective Association. The White Oak earned this honor because of the legendary Charter Oak, a specific tree that stood in Hartford for over 500 years. This famous oak hid Connecticut's Royal Charter in 1687 when British authorities demanded its return, making the tree a powerful symbol of colonial resistance and American independence.
What Is the Connecticut State Tree?
The White Oak holds the designation of Connecticut's official state tree. This hardwood species typically grows 80 to 100 feet tall with a trunk diameter reaching three to four feet. White Oak can live for 300 to 600 years and develops a broad, rounded crown.
The tree's name comes from its distinctive whitish gray bark. Young bark shows thin scales, while older trees develop irregular blocky plates. The light bark color distinguishes White Oak from darker-barked oak species.
White Oak leaves measure five to nine inches long with seven to nine rounded lobes. Acorns mature in a single growing season, ripening from July through September. Each acorn measures about three-quarters of an inch long.
Connecticut State Tree Name
The common name is White Oak. The scientific name is Quercus alba, meaning 'white oak' in Latin. The species name alba refers to the light-colored bark.
The Charter Oak was the specific White Oak tree that made the species famous. This tree stood on Wyllys Hill in Hartford from the 12th or 13th century until August 21, 1856. People estimated it was over 500 years old when a storm knocked it down.
Why the White Oak Became the Connecticut State Tree
Connecticut made official the White Oak as its state tree on April 16, 1947. Representative Edgerton introduced House Bill No. 688. The Connecticut Tree Protective Association lobbied for the legislation. The House approved it March 11, Senate approved March 18, and Governor James L. McConaughy signed it 29 days later.
The White Oak earned this designation because of the Charter Oak's legendary role. On October 31, 1687, Sir Edmund Andros demanded Connecticut return its Royal Charter of 1662. King James II wanted to revoke colonial charters and consolidate control. During the meeting, all candles suddenly went out. Captain Joseph Wadsworth seized the charter and hid it inside the hollow White Oak on the Wyllys estate.
This act of resistance defined colonial courage against British authority. The Charter Oak stood as a symbol of independence for 170 more years. When it fell during a storm in 1856, residents collected acorns and wood. People planted Charter Oak offspring throughout Connecticut. The timber became furniture in Connecticut's State Capitol, including the governor's desk and legislative chairs.
