Anagallis arvensis or scarlet pimpernel is a low-growing prostrate annual plant. It does not compete well with other species so it favours locations where the soil is free from other plants. This common European plant is generally considered a weed and is an indicator of light soils, though it grows opportunistically in clay soils as well. In gardens, this species can 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, hence the common name.
Sow Scalet pimpernel in situ at a depth of 1/4 cm below the soil surface, with a spacing of 12 to 20 cm after the last frost of spring. It requires between 30 days and 45 days to germinate.

Pimpernel does not compete well, so it is best planted on its own with enough space around it to prevent competition from other plants.
