English Oak

Quercus robur (Fagaceae) is a large deciduous tree native to Europe, western Asia, and North Africa. It grows to about 70 feet tall with a massive spread (up to 98 feet) and the deeply furrowed bark and broad, spreading crown that define the archetype of an oak. The classic rounded, shallowly lobed leaves have almost no petiole. Acorns are carried on long stalks (peduncles).

English oak grows in full sun on a range of well-drained soils (pH 4.5 to 8.5) and tolerates moderate drought once established. It is the dominant woodland tree on clay soils across much of Europe. The cultivar 'Fastigiata' offers a narrow, columnar form for tighter spaces. Powdery mildew can be significant in humid conditions. The species is widely planted as a street and park tree. Hardy in Zones 4a to 8b.
