Quercus alba, the white oak, is the grandfather of the eastern forest, a slow, massive, long-lived tree that can stand for centuries and outlast the people who plant them. The most famous of all was the Wye Oak of Wye Mills, Maryland, a single white oak that stood for more than four hundred and sixty years and served as Maryland's state tree until a storm brought the giant down in 2002. The broad, rounded crown, the pale, scaly, ash-gray bark, and the deeply lobed, blue-green leaves are the picture most people carry of an oak.

No native tree has given more. White oak acorns are among the sweetest of the oaks, low enough in tannin that Native peoples across eastern North America gathered, leached, and ground them into a staple meal, and the acorns still feed deer, turkeys, squirrels, wood ducks, and jays every fall. The timber is legendary in its own right, tight-grained and watertight, the wood of ships, barrels, and bourbon casks; the very name white oak conjures the material as much as the tree.

The bark carried the medicine. Rich in tannins, white oak inner bark was one of the great astringents of Native American and settler herbalism, taken for looseness of the gut and gargled for a raw throat, and used externally as a wash for wounds and inflammation. The genus name Quercus is the old Latin for oak, and it hides a small piece of chemistry: quercetin, the antioxidant pigment first drawn from oak, is named for the tree. A fuller account of the traditional uses appears in the medicinal notes below.

In the garden, plant white oak for the long view, the way an earlier generation planted the trees now shading their grandchildren. Give an open, sunny site with deep, well-drained, slightly acid soil and plenty of room for a slow tree that can reach eighty feet and spread as wide, a lawn specimen, a park or estate tree, or the anchor of a native woodland. White oak resents having the roots disturbed once established, so site the tree carefully and let the roots settle undisturbed; underplant only at the outer dripline, and let a great oak become, over decades, the finest thing in the garden.

Flower, Fruit & Foliage

Yellow-green catkins, spring

Flower. Small, wind-pollinated spring flowers opening with the new leaves: slender yellow-green male catkins two to four inches long and tiny reddish female flowers in the leaf axils.

Fruit. Large acorns to an inch long in a shallow, warty cap, ripening brown in a single fall, low in tannin and prized by deer, turkeys, squirrels, and jays.

Foliage. Deeply lobed leaves with five to nine rounded lobes, blue-green above and pale beneath, turning rich red, burgundy, and purple in autumn and often held into winter on young trees.

History & tradition

White oak bark is one of the classic astringents of North American herbal tradition. Native peoples across the East and, later, European settlers valued the tannin-rich inner bark, which runs to six to eleven percent tannin, for its drying, tightening action. Bark decoctions were taken for diarrhea and dysentery and gargled for sore throats and lost voice, and used externally as a wash for wounds, burns, rashes, and hemorrhoids. The bark also carries quercetin, the antioxidant flavonoid that takes its very name from Quercus. Rigorous clinical trials remain few, and the strong tannins make the bark unsuited to casual or prolonged internal use.
