A native of Europe and Africa, the species occasionally escapes from cultivation in the United States and can be found in disturbed places. First collected in the 1892 at Les Cheneaux, Mackinac Co., by W. C. Coryell, who noted that it was probably introduced from Ohio.
A very glaucous plant, this species has lower leaves deeply pinnatifid, the upper ones merely shallowly lobed and toothed with strongly clasping base. The common name refers to the very long fruit (said to attain as much as 40 cm).
