Species	Ulmus pumila
Cultivar	'Dropmore'
Origin	US

The Siberian elm cultivar Ulmus pumila 'Dropmore' [1] was grown from seed collected in Harbin, Manchuria, China, by F. L. Skinner, of Dropmore, Manitoba.^[1] Green reported (1964) a suggestion to merge the Siberian elm cultivars 'Harbin' and 'Manchu' with 'Dropmore', as all came from the Harbin area.^[2] In the event, 'Dropmore' appears to have superseded these earlier cultivars.^[3]

The cultivar 'Chinkota' was raised in North Dakota from 'Dropmore' seed.^[4]

'Dropmore' is a fast-growing bushy form producing small leaves.

See under Ulmus pumila.

The tree remains in commercial cultivation in the United States. Considered cold-hardy far into Canada [2], it did not perform well in the hot, arid, climate of Arizona as part of the elm trials in conducted by the Northern Arizona University at Holbrook[3].
