Ynghylch

Vervain, or verbena as it can be known, is native to South East Europe and was likely introduced here in Neolithic times, so has been long naturalised. It was widely cultivated as a medicinal herb in medieval gardens and has escaped often. It is a tall plant, with branching stems and clusters of small, purple flowers from June through to October. In the wild, it prefers chalky soils and can be seen on rough grassland, roadside verges, scrubby areas, coastal cliffs and waste ground.
