Native to tropical South America, sanchezia is a shade-loving shrub with spiked branches and yellow and red flowers.

It was introduced to Queensland as an ornamental garden plant but has escaped in certain areas. Sanchezia can form dense thickets under rainforest edges.

Sanchezia is not a prohibited or restricted invasive plant under the Biosecurity Act 2014.

Sanchezia parvibracteata


  • Shade-loving shrub about 5m tall.
  • Leaves are dark green, 12-25cm long, 7cm wide.

How it is spread

  • Reproduces vegetatively, with broken fragments easily taking root.
  • Invasions are usually associated with nearby gardens.


Physical control

  • Hand-pull seedlings and small plants, making sure that all roots and stem fragments are removed.

Herbicide control

  • Herbicides are effective.

Legal requirements

  • Sanchezia 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 and animals under their control.
  • Local governments must have a biosecurity plan that covers invasive plants and animals in their area. This plan may include actions to be taken on certain species. Some of these actions may be required under local laws. Contact your local government for more information.
