English oaks are large deciduous trees. Their leaves are an olive green color, lobed, short-stalked leaves 7-14 cm long. The leaves are arranged alternately and have an ear-shaped (auriculate) leaf base. English oaks flower in spring and their fruit, the acorn, is ripe by fall. The acorns are positioned on a peduncle (acorn stalk) with 1-4 acorns on each peduncle. The bark is ridged grey. The largest English oak in New York State is located in Nassau county and stands at 88 feet.
