The Siberian Elm cultivar Ulmus pumila 'Harbin' is an older Manchurian selection,[1] grown from seed collected from an area with a similar climate to that of the Great Plains,[2] and superseded in the United States by 'Dropmore'. Green reported (1964) a suggestion to merge 'Harbin' and the Siberian elm cultivar 'Manchu' with 'Dropmore', as all came from the Harbin area.[3][4]
