Scarlet Pimpernel - Lysimachia arvensis

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 (subsp. arvensis), occasionally pink, but two blue colour forms occur, namely Lysimachia arvensis subsp. arvensis forma azurea and Lysimachia arvensis subsp. foemina, these can only be reliably separated by detailed examination. The flowers close up around 3pm.

The blue subspecies foemina is on the VC55 Rare Plant Register, and therefore a photo is needed for verification

Cultivated, disturbed and waste ground, pathways and gardens.

Fairly common throughout Britain, but mainly coastal in the far north.

Quite common in Leicestershire and Rutland.
