Hemlock warning: the deadly plant found in UK gardens

People are being told to keep an eye out for hemlock, which can be found in our gardens and looks similar to Cow’s Parsley.

If it was eaten, hemlock could kill due to the fatal toxins it contains.

They grow naturally and include gamma-coniceine and coniine, which can cause muscular paralysis.

Ingesting the toxic plant could lead to respiratory failure.

Hemlock usually grows in wet, marshy places and is often confused for its non-poisonous lookalikes such as wild carrots or parsnips.

Plant expert Whitney Bromberg Hawkings told The Sun: "Water Hemlock, which bears a close resemblance to Cow’s Parsley can be found dotted across the countryside the second the sun comes out, but can also be fatal to animals and humans alike within minutes of ingestion.

"It contains a highly poisonous chemical that is lethal if ingested, not to mention its strong carrot-like odour which makes it a garden foe."

Hemlock symptoms and risks

Hemlock can cause horrendous symptoms when ingested.

These include: vomiting, trembling, problems in movement, slow and weak later rapid pulse, rapid respiration, salivation, urination, nausea, convulsions, coma, and even death in domestic animals and humans.

A dog was taken ill and later died while out walking in County Antrim May last year, with the animal's death thought to be possibly caused by exposure to the poisonous plant.
