Invasive weeds alert: Chinese Violet

Chinese Violet
Chinese Violet

Port Macquarie-Hastings Council is urgently calling for all local residents to inspect their properties for a noxious weed called Chinese Violet.

Chinese violet is a rapidly growing and hardy creeper that has the potential to invade many coastal and sub-coastal areas in the region.

 

If left uncontrolled it:

  • completely smothers native ground covers and understorey plants;
  • forms dense and continuous infestations;
  • prevents the germination and establishment of other species;
  • removes habitat for native fauna; and
  • reduces biodiversity and productivity.

For these reasons, Chinese Violet has the highest biosecurity control obligations under the Biosecurity Act 2015 in the state. Residents who have found this plant must contact their local council weeds officer for assistance with identification, control and eradication.

Where are you likely to find it?

Chinese violet is a native of India, the Malay Peninsula and Africa. It was recorded as naturalised near Newcastle in 1999 and South West Rocks in 2009. There is now an isolated infestation in the Hastings region.

It may be found in home gardens as an ornamental, though is banned from sale in NSW.

So far in NSW, Chinese violet has been found in coastal sandy soils, although in the Hastings it has been found on a riverbank in part shade. It has the potential to invade a wide range of environments.

What does it look like?

  • a creeping plant with opposite leaves and lightly hairy stems, growing up to 1m tall
  • Leaves are paler beneath, oval to triangular in shape
  • forms sprawling mats and can clamber over adjacent vegetation
  • stems can root at the nodes in moist soil
  • white bell-shaped flowers 2-2.5cm long with distinct purple blotches in two parallel lines
  • fruit capsules 3cm long and guitar-shaped

If you find Chinese Violet, contact your Council’s weeds officer on 6581 8111 as soon as possible for advice and assistance to eradicate it from your property.

The Biosecurity Risk of this weed to our community and the environment is extreme. For voluntary reported infestations Port Macquarie – Hastings Council’s Invasive Weed Team will provide free inspection and control service of this plant for the first year to assist with identification and eradication.

Chinese Violet  is regulated by a Control Order under the NSW Biosecurity Act 2015 and applies to all residents. The Control Order specifies that individuals must report occurrences of this weed within 24 hours of detection.
