English Oak

Quercus robur


The English Oak is a large deciduous tree 25–35 m tall (exceptionally to 50 m), with lobed and very short-stalked leaves 7–14 cm long. Flowering takes place in mid spring, and their acorns ripen by the following autumn. The acorns are 2–2.5 cm long, have a peduncle or acorn-stalk, 3–7 cm long with one to four acorns on each peduncle. It is a long-lived tree, with a large widespreading crown of rugged branches.


It prefers moist, well-drained, moderately rich soils of variable pH, but adapts very well to moderately dry soils of poor quality. It thrives in full sun to partial sun (but is shade tolerant in youth), and grows in zones 4 to 8.


This is a very young tree. Squirrels and Blue Jays love to eat the acorns.
