Hypericum perforatum (St John's Wort)
St. John's Wort (Hypericum perforatum) is a declared noxious weed in many local government areas of NSW. It is regarded as a significant environmental weed in Victoria and as an environmental weed in the ACT, South Australia, Western Australia and other parts of New South Wales. It is managed to some extent by government and community groups in Victoria, New South Wales and the ACT, and is listed as a priority environmental weed in six Natural Resource Management regions.
It is highly invasive and forms into dense colonies that crowd out native plants. It changes the soil structure to the point where many natives just die out, especially the more delicate ones such as orchids and some lilies and forbs. It is very hard to control since it is able to recover from underground rhizomes which produce new aerial growth each year. In the ACT its spread as been increasing over time and it is a problem in many nature reserves.
Hypericum perforatum is listed in the following regions:
Canberra & Southern Tablelands | Albury, Wodonga | South Coast | Hume | Gippsland
