Taraxacum officinale
Dandelion
Golden heads and white seed clocks are familiar on Irish lawns and verges. This entry covers the common dandelion group rather than its difficult microspecies.

FIELDCRAFT · FIND WITH CARE
Finding guide
Choose the season, find the habitat, then watch patiently. Search guidance is not a measure of rarity or conservation status.
- When to go
- Often flowers March–October, longer in mild conditions.
- Where to start
- Less frequently mown grass in Dublin and other Irish parks. This is not a microspecies identification key.
- What to do when you arrive
- In uncut grass, compare basal toothed leaves, yellow heads and white seed clocks. Check features such as leafless flower stalks visually; this entry does not separate microspecies.
Habitat and behaviour reference: Wildflowers 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.

Seeds and spent flowers
Flowers and ripe seed clocks alternate while rosettes remain at ground level.
Autumn

Foliage and growth
Rosettes continue growing, with renewed flowers and seeds in mild places.
Winter
Dec–Feb

Foliage and growth
Ground-level leaves often persist with few flowers; white seed clocks are not uniquely a winter feature.

FRUIT · SEED · FOOD SAFETY
Fruits, seeds & edibility
Know the structure, then the part. Recognising a plant does not make it food.
Fruit
Photo unavailable
A head of one-seeded fruits with parachute-like pappus, not naked seeds.
Jaiiiiiiii · CC BY 4.0 ↗ License termsThe white clock consists of many cypselae, each with a long beak and a parachute-like pappus.

Seeds & dispersal units
Photo unavailable
A head of one-seeded fruits with parachute-like pappus, not naked seeds.
Jaiiiiiiii · CC BY 4.0 ↗ License termsThe windborne unit is normally a one-seeded fruit, not a seed removed from its fruit wall.
- Food use of this part
- Food safety not established by this guide
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.

How to identify it
A basal rosette, often with backward-pointing teeth; each unbranched hollow stalk carries one yellow head made entirely of strap-shaped florets. Several other daisies look similar.
Where it grows
Lawns, meadows, verges and disturbed ground.
Growth and ecology
A perennial with wind-dispersed seeds; flowers provide food for early insects.
Flowering and seasons
Often flowers March–October, longer in mild conditions.
Where to look
Less frequently mown grass in Dublin and other Irish parks. This is not a microspecies identification key.
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.
