  • Water primrose Ludwigia grandiflora is an invasive non-native plant that is invading our ponds, lakes, wetlands, ditches and watercourses.
  • It was introduced as an ornamental garden plant, but has now been banned from sale.
  • It has already invaded many habitats in Western Europe and Japan, excluding native plants and animals, increasing flood risk, preventing fishing, navigation and reducing the amenity value.
  • In the UK the Environment Agency is coordinating the eradication of water primrose, before it gets too established in the wild.
  • If you have water primrose in your garden, it is a criminal offence to spread it into the wild. Follow the be plant wisecampaign and dispose of it safely.
