Quercus robur (English Oak)
Also known as: Peduculate Oak
Native: Europe including Britain, east Russia, southwest Asia, north Africa
This is the most common of the two native British oaks and is extremely long lived, possibly up to 800 years or more. Valuable for timber, especially in the past when much of Britain was covered in oak forests. Height to more than 30m.
Leaves 10-12.5cm are sessile.
Flowers in May, the female flowers can be seen on the end of the new growth.
Acorns are on long stalks or peduncles, hence the alternative common name which separates it from Quercus petraea, the Sessile Oak. The acorns are 1.8-3cm long and fall in October.
