Chamaenerion

Called “Willowherb” in GBIF

Chamaenerion is a genus of flowering plants in the family Onagraceae. It has sometimes been included in the genus Epilobium. Members of the genus may be called willowherbs, or fireweeds, based on a common name used for C. angustifolium. They are upright herbaceous perennials, growing from a woody base or from rhizomes, with racemes of usually purple to pink flowers. All species are found in the northern hemisphere. Most occur in moist habitats; C. angustifolium is the exception, favouring disturbed ground.
