What weed smells like ginger?

Wild ginger is a weed that smells like ginger (Zingiber officinale). The herbaceous plant in question (Asarum spp) may be found growing natively throughout the temperate northern hemisphere. But unlike ginger root, the kidney-leaved, little jug-flowered member of the birthwort family Aristolochiaceae must not be eaten as wild ginger contains the cancer-causing aristolochic acid.
