Origin
Europe

Ulmus × viminalis Lodd. 'Aurea' is a hybrid cultivar derived from the crossing U. minor subsp. minor Mill. × U. minor var. plotii Druce raised before 1866 by Rosseel of Louvain [1]. It is distinguished by its suffused golden yellow leaves in early summer, greening as the season progresses [2] [3]. However, owing to susceptibility to Dutch elm disease, the tree is probably extinct in the UK [4], although it is still cultivated in the USA. A grafted specimen was grown at Kew before the First World War[5].
