This subspecies of the polymorphic species fontanum (cf. Fl. Eur. 1/1964, p. 142) is considered as originating from Europe and W. Asia. It has then been widely spread as a weed. With its present distribution this subspecies belongs to the circumpolar plants (Hultén, Circumpol. Il, p. 232 and map 224). For subsp. scandicum see no. 748.
