Pampas grass is a large perennial grass native to South America, which was introduced to Australia in the 1800s as an ornamental plant. It is characterised by its sizeable and colourful blade-like fluffy flowers, which burst from grass-like foliage. Pampas grass grows best in full sun and is low-maintenance, drought-tolerant, deer-tolerant, and has few pest problems. It is considered easy to grow and is highly sought after for its rustic look. However, it is also considered an environmental weed in several Australian states, due to its rapid growth and ability to outcompete native vegetation. It is not allowed in certain states, including New South Wales, Tasmania, and South Australia.

Pampas grass is an environmental weed in Australia
Pampas grass, a large perennial grass native to South America, has become an environmental weed in Australia. Introduced to the country in the 1800s as an ornamental plant, windbreak species, and source of fodder, it has since spread across the southern and eastern regions of the country. The grass is cultivated as a garden ornamental in these regions, particularly in Tasmania, Victoria, New South Wales, and South Australia.
Pampas grass has several characteristics that make it highly invasive. It can grow rapidly, produce a large biomass, and generate numerous seeds that can be dispersed over long distances by wind or water. This allows it to outcompete native vegetation and quickly invade disturbed sites, waste areas, forestry plantations, and roadsides. The grass also has a deep root system, with roots recorded at depths of up to 3.5 meters, making it challenging to eradicate.
The grass's dense stands can restrict access for native fauna, humans, and livestock, and its large, flammable flowering spikes create fire hazards. It has the potential to invade and negatively impact a range of environments, including urban bushland, wetlands, swamps, stream banks, grasslands, and coastal areas. Due to these characteristics, pampas grass was included in a list of 71 species nominated by state and territory governments for assessment as Weeds of National Significance (WONS). While it was not ultimately included in the final list of 20 WONS, it is still considered a weed of potential national significance.
Despite restrictions in some states, such as New South Wales, Tasmania, and South Australia, where it is not allowed, pampas grass remains a popular ornamental plant in Australian gardens due to its attractive, feathery flowers and ease of growth. However, its rapid self-seeding and invasive nature can quickly become a problem within landscapes, hogging up space and resources. Mechanical/manual removal of pampas grass is the best method of control, and it should be carried out when the soil is moist to ensure the removal of the entire root system.

It is a highly invasive plant
Pampas grass is a highly invasive plant that has been introduced to Australia, where it is now grown in some gardens as an ornamental plant. It was originally brought to the country in the 1800s as a garden plant, an ornamental, windbreak species, and a source of fodder. Pampas grass can spread large distances from these sources of seed, and its wind-borne seeds can travel up to 30 kilometres. It is a weed of potential national significance and is considered a noxious weed in some Australian states. As a result, it is banned in New South Wales, Tasmania, and South Australia.
Pampas grass has several invasive characteristics, including rapid growth, large biomass accumulation, production of numerous seeds, and long-distance seed dispersal. It can grow to be 6.5 metres tall and has roots that can reach depths of 3.5 metres. Once established, pampas grass is highly competitive with native vegetation, restricting the regeneration of native trees and crowding out native plants by competing for light, water, nutrients, and space. Dense stands of pampas grass can also restrict access for native fauna, humans, and livestock, and create fire hazards.
Pampas grass is an environmental weed that grows in disturbed sites, waste areas, forestry plantations, and along roadsides. It is a problem weed in urban bushland, wet sclerophyll forest, and pine plantations, particularly in moist areas around cities and towns. It has the potential to invade large areas of urban bushland and negatively impact wetlands, swamps, stream banks, bushland, open woodlands, grasslands, and coastal environments.
Mechanical/manual removal of pampas grass is the best method of control when the soil is moist, typically after rain. It is important to remove the entire crown and root system, which can spread out from the plant. Pampas grass can also be controlled through physical, mechanical, grazing, and herbicide methods.

It was introduced to Australia as an ornamental plant
Pampas grass is a large perennial grass native to Brazil, Argentina, Uruguay, and Chile. It was introduced to Australia in the 1800s as an ornamental plant, a windbreak species, and a source of fodder. Cortaderia selloana, or common pampas grass, is still cultivated as a garden ornamental in southern and eastern Australia, particularly in Tasmania, Victoria, New South Wales, and South Australia. Cortaderia jubata, or pink pampas grass, was introduced to Tasmania more recently and has since spread to Victoria.
Pampas grass is a highly invasive plant with the potential to compete with and crowd out local native plants. It has been nominated for assessment as a Weed of National Significance and is considered a weed of potential national significance in Australia. It is also listed in the Global Invasive Species Database. Despite this, it remains a popular ornamental plant due to its attractive, feathery flowers and ease of growth.
Pampas grass can grow to impressive sizes, with some mature plants reaching up to 10 feet tall and 6 feet wide. The large flowering spikes can protrude up to 6.5 meters tall. The grass is characterised by its long, linear foliage, which arches gently to create an attractive form within gardens. The flowers come in a range of colours, including pinkish-white, silvery-white, and variegated hues.
Pampas grass is easy to grow and maintain, making it a great choice for novice and expert gardeners alike. It grows best in full sun or at least half a day of direct sunlight and prefers loamy, moist, and well-drained soil with a neutral to slightly acidic pH. It should be planted in spring, with each plant spaced 2 to 3 meters apart to allow for growth and spread. Once established, pampas grass is low-maintenance, drought-tolerant, and deer-tolerant, with few pest problems. However, it is important to note that the plant self-seeds rapidly and can quickly become invasive.
Due to its invasive nature, the growth and spread of pampas grass are controlled in many regions of Australia. It is prohibited in some states, including New South Wales, Tasmania, and South Australia, and actively managed by community groups in other areas. Despite these restrictions, pampas grass remains a sought-after ornamental plant in Australia, adding colour, texture, and interest to gardens and outdoor spaces.

It is easy to grow and maintain
Pampas grass is an attractive ornamental grass that is extremely easy to grow. However, it is important to know what you are getting into before planting pampas grass. Pampas grass is a fast-growing plant that can become quite large, anywhere from 5 to 10 feet (1.5 to 3 meters) high and wide, and even invasive. Pampas grass was introduced to Australia as a garden plant, an ornamental, windbreak species, and a source of fodder. It can spread large distances from seed sources.
Once established, pampas grass care is minimal and requires little maintenance other than watering in extreme drought. It should be pruned each year to the ground in late winter or early spring. Due to the plant's sharp foliage, pruning should be done with care using gloves and a long-sleeved shirt. Pampas grass can also be burned to the ground without harming the plant, and a balanced fertilizer can be applied to stimulate regrowth. Pampas grass is usually propagated through division in spring, and replanted elsewhere.
Pampas grass is a popular choice for floral arrangements due to its soft, downy texture and long-lasting nature. To style, pampas grass can be cut to size or presented in full height. Heat from the sun or a hairdryer will fluff up the plumes, and hairspray will prevent shedding. To avoid mould, ensure there is good airflow in the space, especially in humid climates.
In Australia, pampas grass is not allowed in New South Wales, Tasmania, and South Australia due to its highly invasive nature. However, it is permitted in other states such as Victoria and Queensland, where it is sought after by florists and decorators for its natural and rustic look.

It is banned in some Australian states
Pampas grass, though widely available in florists worldwide, is considered a noxious weed in several Australian states. It is banned from sale in parts of New South Wales (NSW), including greater Sydney, the Hunter region, the south-east, and the north coast. In these regions, pampas grass is recognised as a highly invasive plant that competes with local native plants, harbours vermin, and poses a significant fire risk due to its large biomass and flammability. The grass produces up to 100,000 seeds per plume, which can spread over long distances, up to 25 kilometres, through wind or water dispersal. This makes it challenging to control and eradicate once established.
In addition to NSW, pampas grass is also banned in Tasmania and South Australia. However, it remains available in other states like Victoria and Queensland, where it is sought after for its natural and rustic aesthetic in floral arrangements and decorations.
The invasive nature of pampas grass has not escaped the notice of authorities. It was included in a list of 71 species nominated by state and territory governments for assessment as Weeds of National Significance (WONS). While it did not make the final list of 20 WONS, it is still recognised as a weed of potential national significance.
Despite the restrictions and its environmental impact, pampas grass remains popular, especially in the wedding industry, due to its aesthetic appeal. This popularity has led to a thriving market for the grass, with sellers active on online platforms. However, some florists and stylists are taking a stand against using pampas grass, recognising the threat it poses to Australia's unique bushland and native environment.
