Quercus robur, commonly called English oak, is native to mixed woodland areas from the British Isles to the Caucasus. It has been widely planted in North America since the 1600s. It is a large, majestic, deciduous oak of the white oak group that typically grows in cultivation to 40-70’ (less frequently 100’) tall with a broad-spreading, rounded crown. Trunks are typically short, with ridged and furrowed dark gray to black bark. Insignificant monoecious yellowish-green flowers in separate male and female catkins appear in spring as the leaves emerge. Fruits are oval acorns (to 1” long) on 1-3” long stalks. Acorn caps extend approximately 1/3 the acorn length. Acorns are an important source of food for wildlife. Short-stalked, dark green leaves (3-5” long) with 3-7 blunt lobes per side are blue-green beneath. Small auriculate lobes at the leaf bases distinguish this species from the similar American species of white oak (Quercus alba). Robur comes from the Latin word meaning robust in reference to the strength and durability of the tree. Quercus robur f. fastigiata is a narrow-upright, columnar, fastigiate form of English oak featuring dense, upright branching that rises at a sharp and narrow angle from the trunk. It typically matures to 50-60′ tall and to 10- 20′ wide. Leaves remain green throughout the growing season with little fall color.
