An oak tree that bears a strong resemblance to Q. palustris, occurring in the wild in the north-east of North America. There it forms a large tree with a broad ovoid crown up to approx. 25 m in height. Cultivated specimens are no taller than approx. 15 m. The shallow grooves in the grey bark are yellow. For this reason the tree is also known as “Yellow oak”. The ovoid leaf is deep pinnately lobed. The lobes are pointed and carry sharp serrations. The leaves are bright green, light green on the underside turning to deep purple in the autumn. The acorns, 1 - 2 cm in size, are elliptical and are one-third to half enclosed by the cupule. This is what most distinguishes it from Q. palustris that has rounded to flattened acorns one-third to a quarter enclosed in the cupule.
