It is a large deciduous tree up to 40 m tall, in the white oak section of the genus (Quercus sect. Quercus) and similar to the English oak, with which it overlaps in range.

Significant botanical differences with the English oak include the stalked leaves, and the stalkless (sessile) acorns. It is found more often than the English oak in upland areas with higher rainfall, but also with lighter soils with better drainage.

Hybrids with the English oak are often found, and are named Quercus x rosacea.ca:Roure de fulla gran cs:Dub zimní da:Vinter-Eg de:Traubeneiche eo:Tigfolia kverko fr:Chêne rouvre la:Quercus robur nl:Wintereik pl:Dąb bezszypułkowy sv:Bergek uk:Дуб скельний
