We are asking for help in recording sightings of yellow-seeded false-pimpernel (Lindernia dubia), an invasive non-native species that is new to Great Britain (GB) and was recently detected in Pulborough, West Sussex.

Yellow-seeded false-pimpernel is an annual plant of wetland habitats, that spreads along waterways with contaminated equipment and could potentially be spread by waterfowl. It is already invasive in parts of Europe and poses a risk to native species and habitats.

We are keen to find out whether yellow-seeded false-pimpernel is found at any other sites in GB, and are asking for help in looking out for this species and recording sightings through iRecord. Growth and flowering times are not known for certain in GB, but plants may be seen from May and flowers from June to October.  

The following awareness raising materials are available to help, we can provide free hard copies if needed:

• An ID sheet and alert poster to help with identification and awareness raising
• Check, Clean, Dry materials to help improve biosecurity and reduce the risk of spreading this plant on equipment

We would be most grateful for help in raising awareness by sharing this information with your networks through newsletters, magazines etc where possible. Thank you for your support.
