A long-lived perennial herb occurring on waste ground as an escape from cultivation or as an introduction in partially shaded habitats, most often near habitation. Lowland.
Introduced into cultivation by 1596, A. major is a popular garden plant and various cultivars are grown. This is the first map showing its national distribution, so changes are difficult to assess. It has been known in the wild near Craven Arms (Salop) since at least 1841.
Native of C. Europe.
