Anagallis arvensis
Scarlet pimpernel has weak sprawling stems growing to about 50 cm long, which bear bright green ovate sessile leaves in opposite pairs. The small orange, red or blue flowers (A. arvensis forma azurea) are produced in the leaf axils from spring to autumn. The petal margins are somewhat crenate and have small glandular hairs. I have added a detail of the crenate petal margin to distinguish it from Blue pimpernel.

Blue-flowered plants (A. arvensis Forma azurea) are common in some areas, such as the Mediterranean region, and should not be confused with the related Blue pimpernel, Anagallis foemina, sometimes treated as a subspecies, Anagallis arvensis ssp. foemina. In 2007, a molecular phylogenetic study showed that Anagallis foemina is more closely related to Anagallis monelli than to Anagallis arvensis, and should be treated as a separate species. The latin name comes from greek άναγελάω, άνάγαλλίς, to laugh intensely. It was said that when hens eat it then they sing euphoric. Camera Model: NIKON D300.
