About the guide

False yellowhead is on the Alert List for Environmental Weeds. This is a list of 28 non-native plants that threaten biodiversity and cause other environmental damage. Although only in the early stages of establishment, these weeds have the potential to seriously degrade Australia's ecosystems.

Originally from the Mediterranean region, it is not clear how false yellowhead was introduced to Australia but it may have escaped from a garden. It was first recorded in Albany in 1955, and has since spread throughout southern Western Australia. It is occasionally found in swamps but mainly occurs in highly disturbed areas such as roadsides, railway lines, fire breaks and walking trails.

False yellowhead is a prolific seed producer and a threat in the higher rainfall regions of southern Australia. It is known to release substances that inhibit the germination of nearby plants, and to be toxic to stock. It can also cause contact dermatitis in people.

This management guide was prepared in 2003. The state and territory contacts in this document may be out of date.
