The cultivar arose from a 1970 crossing of the Siberian Elm Ulmus pumila (female parent) with the hybrid N 215 ('Commelin' × (U. pumila var. arborea × U. minor 'Hoersholmiensis')), the latter grown from seed sent in 1960 to the University of Wisconsin-Madison elm breeding team by Hans Heybroek of the De Dorschkamp Research Institute in the Netherlands.
