Ulmus pumila 'Manchu' 
Summary
The Siberian Elm cultivar Ulmus pumila 'Manchu' was raised by Stewarts Nurseries, Sutherland, Saskatchewan, c. 1951 from seed collected by Mr Ptitsin from near Harbin, China, an area which has a similar climate to that of the Great Plains.[1] Green reported (1964) a suggestion to merge 'Manchu' and the Siberian elm cultivar 'Harbin' with 'Dropmore', as all came from the same area.[2][3]
