Some plants cannot be bought, swapped or sold in the Limestone Coast

The Limestone Coast Landscape Board works to protect the landscape from the impact of declared weeds by preventing the spread of new weeds. The release of declared plants into our landscape threatens primary production and the environment.

Many declared weeds, particularly those that invade bushland, rivers and coasts are escaped garden plants. 

Our Landscape Officers work with plant resellers and raise awareness within the community about the dangers posed by declared weeds being released into the landscape.

Below is a list of the plants considered a threat to the Limestone Coast. These declared plants are banned from being bought, swapped or sold.

Supporting plant resellers to understand plants prohibited from sale

Landscape Officers support plant resellers to understand what declared plants they cannot sell in the Limestone Coast. This includes inspections of businesses such as nurseries and florists for declared plants prohibited from sale.

The inspections, undertaken by authorised Landscape Officers, are just one tool in the prevention of weed spread across the region.

We recognise that there are other ways in which our community buys, swaps and sells plant. This includes online community buy, swap and sell groups. We actively work with the community to improve their understanding of what plants cannot be bought, swapped or sold.

If you suspect you have a declared plant or a declared plant is being offered for sale or swapping

If you think you have a declared plant or believe declared plants are being offered for sale or swap you should contact a Landscape Officer with the Limestone Coast Landscape Board.

Our Landscape Officers will provide assistance with identifying the plant and supporting you or those offering the plant for sale or swap to control and destroy the declared plant if required.

Our Landscape Officers are here to help, talk to them today

Understanding your legal responsibilities

Everyone has a legal obligation to ensure that their activities do not contribute to the spread of weeds.

Declared plants that are considered as a serious threat are prohibited from being bought, swapped or sold in South Australia under Section 188 of the Landscape South Australia Act 2019 (the Act).

Fines of up to $60,000 can apply for individuals not complying with Section 188 of the Act.

When can prohibited plants be sold

It is not prohibited to sell or transport non-living products made from these plants, such as timber from Aleppo pine, or herbal medicines containing horehound. Such products are excluded from the definition of plant under the Act.
