Scarlet Pimpernel - Lysimachia arvensis

Alternative names
Anagallis arvensis
Description

Low prostrate or ascending plant with square stems.  Leaves mostly opposite, oval, pointed with black gland dots beneath, unstalked.  Flowers are 4 to 7 mm diameter, petals with hairy margin, often slightly toothed at apex.  The flowers are usually orangey-scarlet (f. arvensis), but sometimes  blue (f. azurea), pink lilac (f. lilacina) or white (f. pallida).  Care needs to be taken when identifying the blue form (f. azurea) as there is a very similar blue species Lysimachia foemina which can only be reliably separated by detailed examination. The flowers close up around 3pm.

Recording advice

Care needs to be taken when identifying the blue form (f. azurea - RPR) as there is a very similar blue species Lysimachia foemina and the two can only be reliably separated by detailed examination.  If you have found a blue form, either obtain confirmation from a County Recorder before submitting a record, or submit detailed images showing key features.  We recommend that you take and retain a specimen; the County Recorder may wish to see this for confirmation.
