Detectability: easy to find. Paterson’s curse is one of the best known and most easily recognised declared plants. With its spring display of purple flowers, it’s not likely to be confused with any other weed. Its bristly stems and leaf-rosettes are also distinctive.

Who is likely to find it: potentially anyone in the South West Land Division could find Paterson’s curse including biosecurity groups, local government, and any landholder particularly horse owners.

When to find it: easiest to identify when in flower, mainly in spring, but it can flower at other times of year if conditions are favourable.

Where to find it: Paterson’s curse is most common in the Geraldton area and the Swan and Avon Valleys, but can be found down to the south coast and eastward to the Goldfields. It is often found in paddocks and on disturbed soils including roadsides.
