Pampas Grass is illegal in parts of the US because it can be harmful to other plants and animals, as well as humans. It also spreads rapidly, choking out other vegetation and making it difficult for people to walk through.

Pampas grass is a very versatile and multi-functional ornamental grass that can grow in any types of soil and has less maintenance. However, it has negative impact to nature. In spite of its contributions to the world of ornamental designs and landscaping, it has also cons in growing it.

Why is Pampas Grass Illegal – Get to Know its Negative Impact

Behind its elegance and aesthetic appearance, this perennial and ornamental grass has a negative impact to our environment. Some states in the United States such as California, Hawaii and Washington have illegalized growing this grass for many years for safety purposes.
It is also illegalized in other countries such as Australia and New Zealand where summer, spring, and hot temperatures are constant as well as wildfires.

It is not officially illegal in New South Wales, United Kingdom. However, many people stopped growing this grass due to negative social implication of the swinging scandal issue.
According to some UK press, every homeowner with a Pampas grass in their garden or backyard is considered swinger – a person who engages in group sex or the swapping of sexual partners.

Here are the Reasons of its Illegalization and the Negative Impact of Pampas Grass to Our Environment:

  • It is highly flammable – The fluffy and graceful feather-like plumes of Pampas grass are fire-hazard. It is one of the causes of wildfire as it can spread faster due to its dry and fluffy plumes.
  • It is a threat to other plants – Since this grass is invasive and has long, strong roots, it consumes more land area and absorbs the nutrients from the soil.
    Studies show that one pampas grass plant produces as many as 400,000 seeds. Each plume has the capacity to hold up to 100,000 seeds inside, making the nearby plants malnourished. 
  • It is harmful to the birds – Pampas grass has blade-like leaves that may cause physical harm to the birds who feed off of it. It is also dangerous to people when they prune or cut it without wearing protective clothing or gear. 
  • It can be hard to control – Pampas grass is so invasive. It has the ability to overcrowd a landscape and take over other plants nearby. 
  • It’s hard to eliminate – Removing Pampas grass from your garden takes a lot of effort, time and energy. It may take several years to kill it completely.

Is It Illegal To Cut Pampas Grass

Cutting pampas grass (Cortaderia selloana) is a topic that often raises questions regarding legality and environmental impact. Pampas grass, known for its tall plumes and ornamental value, is considered an invasive species in many regions. In the United States, certain states have enacted regulations to control its spread due to its potential to disrupt local ecosystems.

In areas where pampas grass is classified as invasive, cutting or removing it may be encouraged or even mandated by local authorities. This is particularly true in California and Hawaii, where the plant can outcompete native vegetation and contribute to habitat loss. However, regulations can vary widely from one location to another.

If you are considering cutting pampas grass on your property, it’s essential to check with local environmental agencies or extension services for specific guidelines. Additionally, responsible management practices should be followed – such as ensuring that any cuttings are properly disposed of to prevent regrowth and further spread of the species.

My Tip: Wear protective clothing, including gloves, long sleeves, and pants, to avoid contact with the sharp leaves, as they can cause cuts and irritation.

Can you cut and keep pampas grass?

Yes, you can cut and keep pampas grass! It’s actually quite common to harvest pampas grass for use in floral arrangements or as dried decor. When cutting pampas grass, it’s best to do so in late summer or early fall when the plant is fully grown and the plumes are mature.

Here’s how you can cut and keep pampas grass:

  1. Timing: Choose a dry day to cut the grass when the plumes are fluffy and mature.
  2. Tools: Use sharp pruning shears or a pair of garden scissors.
  3. Cutting: Cut the stems as close to the base of the plant as possible. If you’re planning to use it for dried arrangements, you can trim the stems to your desired length.
  4. Preserving: To dry it, hang the stems upside down in a dry, dark place with good airflow for about two weeks. Once dried, pampas grass will keep its fluffy appearance for a long time.

Conclusion

In spite of this grass’s versatility and ability to provide protection from soil erosion, it is being illegalized in some places due to its negative characteristics. Therefore, before you plan to grow Pampas grass in your garden, educate yourself first and get to know the pros and cons of this mysterious ornamental grass.
