Sessile Oak is another oak tree native to Britain, the other being the English oak.

It is also known as the Durmast Oak.


The Sessile Oak can grom up to 30m (100ft) high and lives up to an impressive eight hundred years or maybe even more. It has a liking to acidic soils, and grows mainly in highlands.

The leaves are quite long and thin, with a tapering stalk and base. They have wavy sides, classic of an oak leaf, and shallow indentations on the side and are a dark green.

The acorns sit on the twig unlike the English oak where the acorns hang off the branches.

The leaves and flowers open in April, and the flowers get fertilised and develop into acorns that have either a short stalk or no stalk at all. The acorns that survive being eaten by Squirrels, Pigeons, Pheasants, Mice, etc. germinate the following spring, being given a headstart by the fact that the acorn has grown a good sized root system by the spring, so the seedling can start growing as soon as the weather allows.


Sessile Oak is grown for timber, and for it's acorns, which were, and still are, fed to pigs, during the "pannage" season, when Pigs ar elet out into the woods in the autumn to eat acorns and nuts that fall from the trees. Sessile Oak trees are also grown for timber, because the trunk grows straight, doesn't fork at any given opportunity, and is less prone to epicormic shoots after thinning operations. Epicormic shoots are shoots growing out of the trunk after exposure to light.
