We wanted to let you know about non-native invasive plants that could cause issues and how you can raise any concerns.
Non-native plants tend to have been introduced by people. Many are not a problem but some can spread and threaten native species and ecosystems. When this happens we call these non-native invasive plants.
Why is this important?
Some of these plants can cause structural issues to buildings, are expensive to eradicate and can potentially harm people.
As part of the Wildlife and Countryside Act in the UK it is an offence to plant or help the growth of non-native invasive plants.
What if I have invasive non-native plants in my garden?
Please don’t worry if you do think a plant in your garden or outdoor space is one of these species – , you are not going to be prosecuted simply for having them. We will support you in controlling the plants and take steps to eradicate them. It is our responsibility, with our residents’ help, to ensure these plants don’t spread.
There are three invasive species there are particular important to be aware of. They are;
- Japanese Knotweed – this is not harmful to people though its roots can cause damage to buildings particularly the foundations. It can be spread very easily and needs to be disposed of as controlled waste by a professional contractor.
- Himalayan Balsam – this is not harmful though it is fast growing and can dominate areas suffocating native plants. It is also deemed a controlled waste.
- Giant Hogweed – A close relative of Cow Parsley, the sap it produces can cause severe skin burns.
You can see a full list of the 36 plants on EU Regulation on Invasive Alien Species here. These plants should not be planted or caused to grow in the wild but. They are also banned from sale and gardeners possessing them should undertake measures to control them.
Guidance for gardeners:
- Choose plants for your garden carefully

- Research online for advice on planting.
Most importantly if you are worried that you have an invasive species in your garden, particularly Japanese Knotweed, Giant Hogweed or Himalayan Balsam please report it you your housing officer or property management officer as soon as possible.
