"Narcissus poeticus" has long been cultivated in Europe. According to one legend, it was brought back to England from the crusades by Sir Geoffrey de Fynderne. It was still abundant in 1860 when historian Bernard Burke visited the village of Findern—where it still grows in certain gardens and has become an emblem of the village. It was introduced to America by the late 18th century, when Bernard McMahon of Philadelphia offered it among his narcissus. It may be the "sweet white narcissus" that Peter Collinson sent John Bartram in Philadelphia, only to be told that it was already common in Pennsylvania, having spread from its introduction by early settlers. The plant has naturalized throughout the eastern half of the United States and Canada, along with some western states and provinces.
