Great willowherb Epilobium hirsutum
Great willowherb, as its name suggests, is the largest natural willowherb found in Britain and Ireland.
It is sometimes called 'hairy willowherb' because of its downy stem and this is also the source of its Latin name (hirsutus being Latin for shaggy or hairy).
Great willowherb produces purple-pink flowers with a white centre that can reach up to 2.5 cm in diameter. Its leaves grow opposite each other and clasp around the stem.
Throughout England, Northern Ireland, Wales and south and east Scotland.
Damp areas in grassland, woodland. Pond margins and ditches.
