The sessile oak (or Quercus petraea) is a tree of the fagaceum family which also includes beeches. It is also called the Cornish oak or the durmast oak. It is the official tree of Ireland and the unofficial tree of Scotland and Wales. It is present throughout most of western Europe.

The why

Why does EcoTree plant Sessile Oaks?

The sessile oak hosts many animal species, which is why we plant it. Moreover, we cultivate it for the ease with which it grows in sandy soils and at higher altitudes (up to 1600 meters)


Sessile Oak - Description


The sessile oak is can live from 500 to 1 000 years. It can reach up to 45 m high for a trunk diameter of 2 meters. Its bark has vertical ridges, the grooves are not too deep but are continuous, which allows the rainwater to be brought to the ground. The trees' crown is ample, but quite clear and make of simpler lines than its cousin, the pedunculate oak. The leaves have petioles and detach easily from one another. They have 9 to 12 round shallow lobes. The species is monoic: its male flowers are in long catkins at the base of the leaf blades, whereas the female flowers are minute and in clumps of 2 or 3. Its fruit are acorns that are laid directly on the branches, without any stalk supporting the flower. A stemless flower, or one with a very small stem, is said to be sessile.

Planting & maintenance

The Cornish oak is planted in autumn, usually in November and when there is no frost forecast, in a ditch 3 to 4 times larger than the clump of roots and as deep; The first year, the tree needs to be regularly watered, especially if it is already tall.
