Ulmus 'Regal'
''Ulmus'' 'Regal' is an American hybrid elm cultivar developed by the University of Wisconsin–Madison and released in 1983. 'Regal' was derived from seeds arising from the crossing of the Dutch hybrid clones 'Commelin' and '215' (''Ulmus pumila'' × 'Hoersholmiensis') sent in 1960 by Hans M.
