Quercus alba – White oak, American white oak

View prices and availability
The white oak is the most common tree in the eastern and central United States, where it forms large forests. It is a large tree with an initially broad ovoid crown which eventually grows to 30 m high and wide. The light brown bark flakes off in flat plates. The older the tree gets the more deeply the trunk is grooved. The leaves are elongated-obovate with a long wedge-shaped base. The 3 to 6 pairs of shallow to deep lobes are fairly narrow. Young leaves are hairy and later bare. In summer the leaf is glossy dark green on top and blue-green with short hairs on the underside. In autumn, it turns orange to wine red or brown-red. The tree grows relatively slowly and needs a lot of space. It is an important supplier of timber in the USA. Grows on almost any soil provided it is moist, well-drained and the roots can penetrate deeply.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2024.
