Dark needles and red cup-like arils stand out through the year; columnar Irish yew is a cultivated form of this species.

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: Evergreen throughout the year; red arils on female trees are most obvious in autumn.
Where to start: Irish estates and churchyards, and designated paths in Killarney's yew woodland.
What to do when you arrive: All year, view flat evergreen leaves and reddish bark from established paths. Red arils on female trees add an autumn clue, but fruitless trees can also be Yew. Observe without eating or collecting.

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

What does the map mark?

Markers show approximate public destinations or visitor bases, not individuals, nests, rare plants or exact entrances. Follow the operator’s routes and signs for access.

Operator or specialist guide

NPWS explicitly names Yew, Hazel, Ash and Holly in the yew woodland, reached by an official walk. The marker is only the Muckross visitor base, not an individual tree location.

Before you goUse official routes such as Arthur Young’s Walk and current notices, staying on paths to protect moss and roots. Gardens have separate hours; woodland routes may close for flooding, falling branches or management. Do not collect plants.

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.

Spring

Mar–May

Flowers

Small reproductive structures appear among evergreen needles and paler new shoots.

Summer

Jun–Aug

Evergreen foliage

Dark foliage persists while seeds and arils develop on female plants.

Autumn

Sep–Nov

Fruits

Some female plants carry red cup-like arils around poisonous seeds.

Winter

Dec–Feb

Evergreen foliage

Needles persist; remaining red structures depend on the plant's sex and bird feeding.

FRUIT · SEED · FOOD SAFETY

Fruits, seeds & edibility

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

Aril, not a true fruit

No true fruits: the red fleshy cup is an aril, not a berry.

Food use of this part: Do not eat

Seeds & dispersal units

One hard seed is visible through the aril opening; the seed is poisonous and must not be eaten.

Food use of this part: Do not eat

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.

BOTANICAL NOTESPlant notes

How to identify it

Flat soft needles often arranged in two ranks. Female trees may bear red cups around single seeds, rather than ordinary berries.

Where it grows

Old woods, estates, churchyards and clipped hedges.

Growth and ecology

A long-lived evergreen. Leaves and seeds are highly poisonous; do not eat any part or leave cuttings accessible to pets or livestock.

Flowering and seasons

Evergreen throughout the year; red arils on female trees are most obvious in autumn.

Where to look

Irish estates and churchyards, and designated paths in Killarney's yew woodland.

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.
