Connecticut State Tree: White Oak

The white oak tree (Quercus alba) is one of the continent’s predominant native hardwood tree species appearing throughout Eastern North America’s forests.

While it will not disappoint as a design feature, oaks are among the most valuable native trees we can plant. The white oak provides a habitat and food for countless species of wildlife. The white oak is the best tree to plant to attract butterflies and it supports hundreds of species of caterpillars. If you want to support pollinators and attract birds, planting white oaks will ensure that will happen. Besides being important for the environment, the tree makes barrels and ages various spirits such as bourbon, whiskey, and wines.

If you have the room and the time to commit—it can live 500 years—the white oak tree is a beautiful and invaluable addition to a landscape for its aesthetic value and role in the local ecosystem.

How to Identify White Oak Trees

White oaks are easy year-round by their height, rounded canopy, and big trunk. They are large trees that grow to 50 to 75 feet tall with rounded canopies. It has a large trunk, often 3 to 5 feet around. The tree’s bark is a light, scaley gray that flakes off in small pieces if picked.

The foliage of the white oak is very recognizable; it has simple, alternating, lobed leaves that are 5 to 9 inches long with rounded tips. In spring and summer, the leaves are dark green on the top with a white or pale green underside. In the fall, the leaves turn reddish brown and linger on the branches late into winter.
