Sorrel usually grows on acidic soil. The species are often considered weeds . However, some species, such as the sorrel , have edible leaves that are used in salads . Field sorrel is also the main component of eel in the green (Wikipedia)
It's nice to see a full field of sorrel. Lovely green leaves and red blooms. And this shot is nice with the line of trees in the background. Fav (And great info, Ferry. Thank you).
