Yellow-seeded false pimpernel (Lindernia dubia) is new to Great Britain (GB) and was detected in Pulborough, West Sussex, earlier this year. This species 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.
The Non Native Species Secretariat is keen to find out whether yellow-seeded false-pimpernel is found at any other sites in GB, and is 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:
• An ID sheet and alert poster to help with identification and awareness raising
