Jolie plante basse rampante aux fleurs minuscules en étoiles, mais hautement toxique aux bêtes. Autrefois utilisée dans la médicine populaire contre les ulcères et une gamme d'autres conditions. La couleur peut varier: rouge, corail, bleu ou blanc.
Tiny white stars, low-growing creeping plant, flowers abundantly in the top meadow of this garden. Flowers open in the sunshine, close in overcast conditions., which has earned this plant the folk name Shepherd's Weather Glass Formerly used in folk medicine, the plant is toxic to grazing animals. The herb and its seed contain saponins, which could explain why fresh material is strongly haemolytic. The root yields the triterpenoid glycoside cyclamin which is highly toxic. The colours of the pimpernel vary widely, from scarlet through rose to blue and white.
There is a novel, The Scarlet Pimpernel, by Baroness Emma Orczy, where the hero, Sir Percy Blakeney, uses The Scarlet Pimpernel as his pseudonym
