Tree Leaf IdentifierWhite Oak
What does a white oak leaf look like?
White oak (Quercus alba) has fingerlike, rounded leaf lobes without bristles. Northern red oak has pointed, bristle-tipped lobes instead. Check several leaves and attached acorns; rounded lobes alone do not distinguish white oak from every other oak species.

Quercus alba
White Oak is a majestic North American oak with rounded leaf lobes and pale gray bark. It is long-lived and produces sweet acorns favored by wildlife. Also known as Stave oak.
How to identify a White Oak leaf
Leaves are 12–23 cm long with 7–9 rounded, bristle-free lobes and a pale underside.
Where it grows
White Oak is native to Eastern and central North America.
Seasonal interest
Foliage develops wine-red to brown autumn tones; acorns mature in one season.
Safety note: Acorns contain tannins and can be harmful to livestock in large amounts.
Can a photo identify this tree?
A photo can provide a useful starting point, especially when the leaf is sharp and well lit. For a reliable identification, compare the result with the leaf edge, lobe pattern, vein structure, bark, buds, fruit, and the tree's location.
Check similar leaves
Compare more than one feature and photograph the twig or attached fruit when possible. Use a regional field guide to check lookalikes.
