Highlights

Respected 20th century naturalist Donald Peattie once said, “If oak is the king of trees, as tradition has it, then the white oak, throughout its range, is the king of kings.” It is a bold statement to be sure, but many agree with him. Perhaps this is why it is the state tree of Connecticut, Illinois and Maryland.

This beautiful tree can be found presiding over pastures, providing shade in urban parks and suburban neighborhoods and thriving in natural stands throughout the eastern United States and southeastern Canada.

Wildlife Value

The acorns are one of the best sources of food for wildlife and are gathered, hoarded and eaten by birds, hoofed browsers and rodents. Leaf buds also are eaten by several bird species, and all parts of the tree are a favorite food for deer.

History/Lore

The white oak forever earned its place in history books when it was combined with other oak lumber to build the famous USS Constitution (also known as “Old Ironsides”). And even in World War II, white oak served our country as the keels of mine sweepers and patrol boats.

It was (and still is) also preferred wood for those beautiful wooden barrels found in wineries and whiskey distilleries across the United States. Why? Strength and durability are important factors, but this choice is also due to microscopic tissues called tyloses that ‘plug’ the vascular cells of the wood, sealing in the barrel’s liquid contents.
