Species Ulmus minor
Cultivar 'Viminalis Aurea'
Origin Louvain, Belgium

The Field Elm cultivar Ulmus minor 'Viminalis Aurea', probably a "golden" form of Ulmus minor 'Viminalis',[1] was raised before 1866 by Egide Rosseels of Louvain,[2] who was known to have supplied 'Viminalis'.[3]

Description[edit]

The tree is distinguished by its 'Viminalis'-type leaves (4–7 cm x 3 cm) suffused golden yellow in early summer, greening as the season progresses.[4][5][6] Rehder noted that 'Viminalis Aurea' has been distinguished from 'Viminalis' by the more deeply incised usually obvate leaves, but the two forms of leaves pass gradually into each other and may be found even on the same plant.[7]

Pests and diseases[edit]

'Viminalis Aurea' is very susceptible to Dutch elm disease.

Cultivation[edit]

One tree supplied by the Späth nursery of Berlin was planted in 1899 at the Dominion Arboretum, Ottawa, Canada, as U. campestris antarctica aurea.[8] Three specimens were supplied by Späth to the Royal Botanic Garden Edinburgh in 1902 as U. antarctica aurea, and may survive in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm).[9] The current list of Living Accessions held in the Garden per se does not list the plant. Only two specimens are known (2016) to survive in the UK, a stunted tree at Borde Hill, West Sussex.[10] and a small tree (2016) at Grange Farm Arboretum (see Accessions). Others are known in Europe and Australasia (see Accessions).
