Japanese honeysuckle is an aggressive scrambling shrub. It has become a serious weed in moist gullies, forests and bushland.
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.
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:
Japanese honeysuckle is a semi-deciduous shrub, climbing or scrambling to 10 m high. The leaves are opposite along the stem, oblong to oval shaped and up to 8 cm long and 4 cm wide. The fragrant white flowers are in pairs, with two lips. The upper lip has 4 lobes. The fruit are oval shaped, black when ripe and up to 1 cm long.
Japanese honeysuckle has naturalised in eastern parts of NSW and is especially common in the Greater Sydney region.
It is native plant in eastern Asia.

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. |
