• Crowds out native vegetation forming dense populations.

Social

• The pollen may cause allergic rhinitis and trigger airway conditions in susceptible people.

• Spreads mainly by bird-dispersed seeds.

The best form of control is prevention. Treat weed infestations when they are small—do not allow them to establish.

• Mock orange is not a prohibited or restricted invasive plant under the Biosecurity Act 2014. However, by law, everyone has a general biosecurity obligation (GBO) to take reasonable and practical steps to minimise the risks associated with invasive plants under their control.
• Local governments must have a biosecurity plan that covers invasive plants in their area. This plan may include actions to be taken on mock orange. Some of these actions may be required under local laws. Contact your local government for more information.
