English Oak (Quercus robur)
is a deciduous tree that is hardy to zone 4 and prefers full sun. It can grow to 90 feet
and has a short trunk and wide, open crown. English oak is tolerant of acidic to alkaline
soils and urban growing conditions. It grows only a foot or so a year but can live more
than 700 years.
Foliage consists of green
unstalked leaves, 3 to 4½ inches in length, with 3 to7 pairs of rounded lobes. They hold
through winter, falling off then with not much color change.
Acorns are elongated and
stalked. They are about an inch long, with a cup that covers 1/3 of the nut, and are borne
singly or in clusters of 2-5.
Nuts provide winter food for many birds and
