Sessile Oak

The sessile oak (Quercus petraea) is part of the fagaceum family of flowering plants that also includes beeches and chestnuts. You may also know the sessile oak as the Cornish, Irish, or durmast oak, as it is the official tree of Ireland and an unofficial emblem in Wales and Cornwall. You can find the sessile throughout most of Western Europe, including in many EcoTree forests.

Why does EcoTree plant sessile oaks?

The sessile oak is a deciduous tree important both ecologically and economically, as it is traditionally used for building materials. We cultivate it since it grows well in sandy soils, at high altitudes up to 1600m, and in dry and poorly-lit climates. More resistant to drought than the English oak, and hardly affected by parasites or disease, the sessile oak is well-suited for resisting climate change.

Sessile Oak - Overview

Sessile Oak - Overview

A sessile oak can live for 500–1000 years and reach up to 45m in height with a trunk diameter of 2m. Its bark has vertical ridges with grooves that run along its length and allow rainwater to make its way to the ground. It has a bright yet ample canopy made up of branches less twisted than its cousin, the English oak. Its leaves grow on small stalks shallow-lobed leaves that easily detach from their petioles or stalks.

It is a monoecious species, with male flowers in long catkins at the base of the leaf blades, and small female flowers found in clusters. The sessile – which means stalkless – produces acorns attached directly to the twig.

Sessile Oak - Species requirements

Less adapted to cool, coastal areas than the English oak, the sessile oak requires less light and fares better in periods of drought. This makes its zone of distribution remain in sub-Atlantic regions. A hill-bound species, it can be found up to altitudes of 1600m. It grows in stony sand, clay, and lime soil, but does best in thick, lightly acidic soil: silts or sand.

The sessile oak is planted in autumn, usually November, well away from periods of frost, in holes 3 to 4 times larger than and as deep as their root ball. During its first year, the tree must be watered regularly, especially if it's grown tall already.

Sessile Oak Wood

The sessile oak has a high-quality wood that is both very solid and easy to work with. Traditionally, the wood has been used for building materials, shipbuilding, and making furniture.

Sessile Oak Symbolism

The sessile oak has come to symbolise strength, power, and generosity. With such a long lifespan, it’s ever present throughout most of our lives, making it the perfect sustainable birthday gift. What better way to celebrate a long-lasting relationship than with a unique and living gift for a happy occasion?
