Scarlet Pimpernel – Anagallis arvensis

This is a small pretty annual which I sometimes come across on my walks. The brilliant red petals are only 4 to 7mm wide, and the plant only grows ups to 15cm tall. It is also known as ‘Poor Man’s Weather-glass’, for the flowers will only open when the sun is shining.

It flowers May to September, and grows on wasteland, fields and coastland. It is widespread and generally common.
