Quercus robur - English Oak or Pedunculate Oak

The Deepdale Jubilee Tree

To celebrate Her Majesty’s Diamond Jubilee, what better tree to choose than the English Oak, a classic national emblem.

Quercus robur is commonly seen throughout British woodlands, parks and gardens and is native to Europe and parts of Northern Africa. It is a large, deciduous tree with a broad crown of strong branches.

Flowering occurs mid spring in the form of catkins and the acorns following this are borne on long stems, called penduncles, ripening in the autumn. The most recognisable feature of English oak has to be its leaves. They have 4-5 deep, smooth edged lobes on either side with two smaller ones where it joins the stalk.

Quercus robur naturally live for many centuries. Some of the oldest trees are ones that have been pollarded or coppiced, a method which seems to extend their life. The trees are also very important to nature as they support the largest number of different life forms than any other British tree. Over 300 lichens and over 400 insect species live on or within the oak tree itself and the insects and acorns then provide a valuable food source for birds and small mammals.
