Pimpernel is a low-growing prostrate annual plant. It does not compete well so it favours places where the soil is almost free of other plants. This common European plant is generally considered a weed and is an indicator of light soils, though it grows opportunistically in clayey soils as well. In gardens Pimpernel should be displayed with pride at the front of borders and rockeries. The flower is most widely known as the emblem of the fictional hero the Scarlet Pimpernel.
