Praxelis (Praxelis Clematidea) is a Declared pest in Western Australia and must be reported.

If established, Praxelis may impact crops, horticulture, pastoral grasslands and native vegetation, seriously degrading agricultural production and Australia’s sensitive ecosystems.
The weed produces thousands of tiny seeds which are easily spread in the wind.
