Hemlock is an upright herb with hollow stems, fern-like leaves and white flowers. It is highly toxic to people and animals.
Hemlock is a robust biennial herb growing 1-2.5 metres high, with hollow stems that have reddish-brown or purple spots on the outer surface. The leaves have a sharp offensive odour when crushed.
It is a weed of disturbed areas, often occurring near stockyards and along roadsides and riverbanks.
Hemlock is native to Europe, China and northern Africa.
Hemlock is highly toxic to livestock and humans, but is avoided by livestock. In humans it is capable of causing serious illness or death, and all parts of the plant are poisonous when ingested. Symptoms include nervousness, trembling and then respiratory distress.

All of NSW | General Biosecurity Duty All pest plants are regulated with a general biosecurity duty to prevent, eliminate or minimise any biosecurity risk they may pose. Any person who deals with any plant, who knows (or ought to know) of any biosecurity risk, has a duty to ensure the risk is prevented, eliminated or minimised, so far as is reasonably practicable. |
