Origin Louvain, Belgium

Ulmus × viminalis Lodd. 'Aurea' is a hybrid cultivar derived from the crossing U. minor × U. minor 'Plotii' raised before 1866 by Rosseel of Louvain.[1]

Description[edit]

The tree is distinguished by its suffused golden yellow leaves in early summer, greening as the season progresses.[2][3]

Pests and diseases[edit]

'Aurea' is very susceptible to Dutch elm disease.

Cultivation[edit]

Only two specimens are known (2016) to survive in the UK, a stunted tree at Borde Hill, West Sussex.[4] and a small tree (2016) at Grange Farm Arboretum (see Accessions). Three specimens were supplied by the Späth nursery to the Royal Botanic Garden Edinburgh in 1902 as U. antarctica aurea, and may possibly survive in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm).[5] The current list of Living Accessions held in the Garden per se does not list the plant. Others are known in Europe and Australasia (see Accessions).
