Eichornia crassipes (Water hyacinth), Lagarosiphon major (Elodea crispa) and Lysichiton americanus (Skunk Cabbage) are on the EU banned list of Invasive Alien Species published in 2016.
The transitional period to allow retailers to sell their stock to the general public ends on 2nd August 2017.
- After this no retailer will be able to sell any of these plants and you may not introduce these plants to your garden from any source.
- If you already have any of these plants in your garden pond you are permitted to keep them but it could be an offence to allow or encourage their spread outside your garden or to release them into natural waterways where they could cause environmental damage.
- There are no imminent changes to this legislation even though the UK has voted to leave the EU. We still have a legal obligation to comply with this EU law.
The Be Plant Wise scheme gives more information on the care that should be taken with banned species.
