Another four pond plants are to be banned from sale by the EU with transitional arrangements enabling their sale for a year provided contractual arrangements ordering stock are put in place before 1 August 2017.

The latest four plants to be banned as part of an update to the Alien Invasive Species Regulation are:

  • Alternanthera philoxeroides (Alligator weed)
  • Elodea nuttallii (Nuttall’s waterweed)
  • Gunnera tinctoria (Giant Rhubarb)
  • Myriophyllum heterophyllum (Broadleaf watermilfoil)

Garden centres and other retailers are also being reminded that all stock of four pond plants banned last year – including water hyacinth – must be cleared from the shelves from 2 August and cannot be sold anymore.

Ornamental Aquatic Trade Association chief executive Dominic Whitmee said: "These are not big sellers in our industry but nevertheless it is yet more aquatic plants being chipped away from what can be sold. And we know the EU is already working on its next list of invasive species and there will be more aquatic plants and ornamental fish being considered for that.

"We would suggest plant growers, wholesalers and retailers read the Defra advice on this and put in an order before 1 August if they want to continue to sell these for the next pond season in 2018.

"And we also need to remind the industry that Eichhornia crassipes, Cabomba caroliniana, Lagarosiphon major and Lysichiton americanus must not be sold from 3 August 2017.

"We continue to make the point to Defra that many of these pond plants do not pose an invasive issue for the UK because they cannot survive our winters so should be allowed back on sale as soon as possible following our exit from the EU."

  • Water Fern (Azolla filiculoides)
