Japanese honeysuckle (Lonicera japonica)

Profile

Impact

Japanese honeysuckle is a robust scrambler or climber that smothers and out-competes native vegetation and prevents the regeneration of native species. It has become a serious weed in moist gullies, forests and bushland.  

Toxicity

Japanese honeysuckle is toxic to humans, causing discomfort and irritation but is not life threatening. The berries and leaves are poisonous if ingested, causing gastro-intestinal irritation. It is also a skin irritant causing rashes on contact with the plant.

What to do if poisoning occurs:

  • If the patient is unconscious, unresponsive or having difficulty breathing dial 000 or get to the emergency section of a hospital immediately.
  • If the patient is conscious and responsive call the Poisons Information Centre on 13 11 26 or your doctor.
  • If going to a hospital take a piece of the plant for identification.

Description

Japanese honeysuckle, native to East Asia is an aggressive semi-deciduous shrub, climbing or scrambling to 10 m high.
