Ulmus × viminalis 'Aurea'
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].
Description
The tree is distinguished by its suffused golden yellow leaves in early summer, greening as the season progresses [2][3].
Pests and diseases
'Aurea' is very susceptible to Dutch elm disease.
Cultivation
A grafted specimen was grown at Kew before the First World War[4]. 'Aurea' is now almost certainly extinct in the UK [5], however several specimens still survive in arboreta in the USA, Denmark, and Australia.
