Water primrose Alert!

We need you to report any sightings of this plant.

If you think you have found water primrose, ‘check the identification’ then send a photo and location details to: alertnonnative@ceh.ac.uk

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 wise’ campaign and dispose of it safely.
