Quercus robur

Pedunculate Oak

A broad crown and rounded leaf lobes make this oak a familiar shape in old woods and parks. Also called English oak, it is native to Ireland too.

Some plants are poisonous. Do not identify by a photograph alone, and never taste them.

FIELDCRAFT · FIND WITH CARE

Finding guide

Habitat first

Choose the season, find the habitat, then watch patiently. Search guidance is not a measure of rarity or conservation status.

When to go
Leaves and flowers in spring; acorns in autumn; branching structure in winter.
Where to start
Seek mature trees in Irish lowland broadleaf woods and old parks. Check leaf and acorn stalks rather than relying on the tree's outline.
What to do when you arrive
Check short leaf stalks and leaf bases in summer, then stalked acorn clusters from the ground in autumn. Compare with Sessile Oak without climbing or breaking branches; hybrids may be difficult.

Habitat and behaviour reference: Tree Council of Ireland ↗ · The practical steps are editorial advice based on the references, not live sightings.

ONE PLANT · FOUR SEASONS

One plant. Four seasons.

Look beyond the flowers: fresh leaves, fruits, bare stems and dormancy.

Meteorological seasons: spring March–May, summer June–August, autumn September–November and winter December–February. Irish weather, cultivar, pruning and plant age affect timing and appearance.

Photos illustrate the relevant feature, not the same plant photographed through a year in Ireland. Features shared across seasons, such as evergreen leaves, may use the same reference. Missing reliable photos are marked; dormancy is not death.

FRUIT · SEED · FOOD SAFETY

Fruits, seeds & edibility

Know the structure, then the part. Recognising a plant does not make it food.

Some seed references show intact one-seeded fruits or dispersal units, as identified in their captions. A whole-fruit photo is not a close-up of the enclosed seed. Cones and arils are not true fruits of flowering plants.

Sources & limitations

No field detoxification methods or safe doses are provided. Never taste a plant to identify it or eat treated or contaminated specimens. Seek professional help after suspected accidental ingestion. National Poisons Information Centre, Ireland ↗

BOTANICAL NOTESPlant notes
01

How to identify it

Leaves have very short stalks and often ear-like lobes at the base; acorns sit on conspicuous long stalks. Sessile oak has short-stalked acorns and longer leaf stalks, and hybrids can occur.

02

Where it grows

Lowland woodland, fertile and relatively moist soils, hedgerows and large parks.

03

Growth and ecology

A long-lived deciduous tree supporting many insects, mosses and lichens. Acorns provide food for birds and mammals.

04

Flowering and seasons

Leaves and flowers in spring; acorns in autumn; branching structure in winter.

05

Where to look

Seek mature trees in Irish lowland broadleaf woods and old parks. Check leaf and acorn stalks rather than relying on the tree's outline.

Seasons vary with weather and location. Suggested habitats are places to look, not guaranteed sightings. Photos show only some features; check leaves, flowers, fruits and specialist references together.
