I am sure most of use are familiar with the common 'weed', the scarlet pimpernel; its colour makes it one of our most distinctive flowers. Lesser known is the yellow pimpernel (Lysimachia nemorum) which is similar in shape and structure but obviously a very different colour. The two are both members of the primrose family although not closely, the yellow pimpernel is a loosestrife.
The yellow pimpernel is a low, creeping plant of damp woodlands and is fairly common on heavy soils where moisture is retained for much of the time. The Latin name 'nemorum means 'of a grove or glade'. The flowers occur at the end of short stalks and have five petals with a small gap between the each. The flowers remain closed in poor light and only open in direct sunshine. The leaves are pointed and a dull green colour and that helps to differentiate this species from creeping Jenny.
There is not much information the uses of this plant that I can find however it is considered to be an astringent herb used to stem bleeding.
