What You'll Learn
Dwarf pampas grass is banned in New South Wales, Tasmania and South Australia
Pampas grass, a large-growing perennial flowering plant, is considered a noxious weed in several Australian states and territories. It is a highly invasive plant that competes with native vegetation, harbours vermin, and is a fire hazard. Each flower head can produce up to 100,000 seeds, which can spread up to a 25-kilometre radius, making it difficult to control and eradicate.
In the 1970s, the New South Wales (NSW) government banned pampas grass and launched an education campaign urging gardeners to remove the plant from their gardens. This campaign was largely successful, and pampas grass was nearly eradicated from Sydney and NSW. However, in recent years, there has been a resurgence of pampas grass in these areas due to neglect and regulatory failures. It is now commonly seen along Sydney's railway lines and freeways, with infestations spreading throughout the city.
As a result of the ongoing challenges with pampas grass in NSW, it is banned from sale in the Greater Sydney, Hunter, southeast, and north coast regions of the state. Biosecurity officers with local governments have compliance responsibilities for managing obligations to control invasive plants like pampas grass. However, their performance has been criticised as inconsistent and ineffective.
In addition to NSW, pampas grass is also banned in Tasmania and South Australia. These states recognise the potential for pampas grass to outcompete local native plants and the environmental risks associated with its invasive nature.
While pampas grass may be sought after for its natural and rustic look, particularly in the wedding industry and by florists, its sale and propagation remain prohibited in these states due to its detrimental ecological impact.

It is considered a noxious weed in several Australian states
Pampas grass is considered a noxious weed in several Australian states. In New South Wales, Tasmania, and South Australia, it is not allowed. It is also banned from sale in parts of NSW, including Greater Sydney, the Hunter region, the south-east, and the north coast.
Pampas grass is a highly invasive plant with the potential to compete with and displace local native plants. Each flower head can produce up to 100,000 seeds, which can spread up to a 25-kilometer radius, posing a significant risk of fire. The seeds are easily picked up by the wind and can quickly infest new areas, making it challenging to control and eradicate.
In the 1970s, the NSW government banned pampas grass and ran a successful education campaign to encourage gardeners to remove the plant from their properties. However, in recent years, there has been a resurgence of pampas grass in Sydney and other parts of NSW due to neglect and regulatory failures.
The wedding industry has been blamed for the increasing popularity of pampas grass, with brides seeking the plant for their decorations. This has led to a mixed response from florists, with some refusing to use it due to its illegal status and environmental impact, while others continue to sell it, creating a challenging economic situation.
The resurgence of pampas grass highlights the need for stronger weed management practices and regulations to protect native species and prevent the spread of invasive plants.

The NSW government banned the plant in the 1970s
Pampas grass, a large-growing perennial flowering plant, is considered a noxious weed in several Australian states and territories. It is native to South America and is highly invasive, competing with native vegetation, harbouring vermin, and presenting a fire risk.
In New South Wales, the NSW government banned pampas grass (Cortaderia species) in the 1970s. The government recognised the plant as a threat to local ecosystems and launched an effective education campaign urging gardeners to remove it from their gardens. The campaign was largely successful, with plant nurseries stopping sales and Sydney rapidly becoming pampas grass-free.
The ban was enforced due to the plant's invasive nature. Pampas grass can self-seed rapidly, outcompeting native plants for space and resources. Each flower head can produce up to 100,000 seeds, which can spread over a 25-kilometre radius, easily picked up by the wind and carried long distances. This makes it challenging to control and eradicate, as the seeds can germinate in new locations, leading to the plant's rapid spread.
Despite the initial success of the 1970s ban, pampas grass is now experiencing a resurgence in NSW. Neglect and regulatory failures have allowed the plant to make a comeback, with sightings increasing in Sydney and beyond. This rebound highlights the need for renewed efforts to manage and control the spread of this invasive species.
It is important to note that the regulations regarding pampas grass vary across Australia. While it is banned in NSW, Tasmania, and South Australia, it is allowed in other states like Victoria and Queensland. However, even in states where it is permitted, it is essential to exercise caution when cultivating pampas grass and prevent its uncontrolled spread to minimise its impact on native ecosystems.

It is a highly invasive species that competes with native vegetation
Pampas grass is native to South America and is considered a weed in most Australian states and territories. It is a highly invasive species that competes with native vegetation. The plant is banned in New Zealand because of its ability to outgrow and displace native plants.
In Australia, pampas grass is not allowed in New South Wales, Tasmania, and South Australia. It is considered a noxious weed in several states and is banned from sale in parts of New South Wales, including Greater Sydney and the Hunter region. The grass produces an incredible number of seeds—up to 100,000 seeds per flower head—and these seeds can spread over a 25-kilometre radius, posing a significant risk to native flora.
The NSW government banned pampas grass (Cortaderia species) in the 1970s and ran a successful education campaign that encouraged gardeners to remove the plant from their properties. However, due to neglect and regulatory failures, pampas grass is making a comeback in Sydney and other parts of New South Wales.
The seeds of pampas grass are easily picked up by the wind and can travel long distances, quickly infesting new areas. When infested sites are developed, there are often no controls to prevent seed-contaminated soil from being dumped elsewhere, allowing the spread of this invasive species to continue.
The invasive nature of pampas grass poses a serious threat to Australia's native vegetation by competing for space and resources. It is important for those in the wedding industry and florists to steer clear of using pampas grass and instead opt for native plants that do not pose a risk to the environment.
