Wild carrot or Poison hemlock: how to tell them apart?
Wild carrot and Poison hemlock look alike and are often mixed up. Here is how to tell them apart, feature by feature, with their photos and the details to look for.
⚡ The quick answer
Wild carrot
Daucus carota
Poison hemlock
Conium maculatum
Wild carrot has a hairy stem and smells of carrot when crushed, whereas hemlock has a hairless stem, often blotched with reddish purple at the base, and a foul smell. These are good clues, but none is a guarantee on its own: if in the slightest doubt, never eat a wild Apiaceae.
🍃 Leaves
Finely divided, fern-like, smelling of carrot when crushed
Alternate, finely divided (3 to 4 times pinnate), bright green, hairless, giving off a foul smell when crushed
🌸 Flowers
White in a flat umbel, often with a single dark purple central flower
Small white flowers in compound umbels
🍎 Fruits
Small achenes bristling with hooked spines
Small ribbed fruits, grey-green when ripe
🪵 Bark
Biennial herbaceous plant with an upright stem, branched in the upper part.
Biennial plant with a hollow, grooved, hairless (smooth) stem, blotched reddish-purple at the base
📏 Size
30 cm to 1 m tall
1 to 2.5 m tall
🗺️ Habitat
Dry meadows, banks, path edges
Waste ground, roadsides, ditches, rubble, nitrogen-rich soils
⚠️ Toxicity
Root edible at maturity; beware of confusion with other Apiaceae, some of which (hemlock, water-dropworts) are highly toxic. Never eat a wild Apiaceae on appearance alone, especially at the vegetative stage before flowering.
Extremely toxic, potentially fatal even at a low dose. All parts contain powerful alkaloids (coniine and related compounds), most concentrated in the seeds and roots. Never consume or handle without absolute certainty of identification.
🔎 And from the Poison hemlock side
Hemlock has a hairless (smooth) stem, often blotched reddish-purple at the base, and a foul smell when crushed, whereas wild carrot has a hairy stem and a carrot smell. These are good clues, but none is a guarantee on its own: if in the slightest doubt, never eat a wild member of the carrot family (Apiaceae).
