SpeciesUlmus minor
Cultivar'Viminalis Aurea'
OriginLouvain, Belgium

TheField ElmcultivarUlmus minor 'Viminalis Aurea', probably a "golden" form ofUlmus minor 'Viminalis',[1] was raised before 1866 by Egide Rosseels ofLouvain,[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] Clibran's of Altrincham (see 'Cultivation') described the coloration as "golden-bronze".[7]Rehder noted that 'Viminalis Aurea' has been distinguished from'Viminalis' by the more deeply incised usually obovate leaves, but the two forms of leaves pass gradually into each other and may be found even on the same plant.[8][9]

Pests and diseases

[edit]

'Viminalis Aurea' is very susceptible toDutch elm disease.

Cultivation

[edit]

One tree supplied by theSpäth nursery of Berlin was planted in 1899 at theDominion Arboretum,Ottawa, Canada, asU. campestris antarctica aurea.[10] Three specimens were supplied by Späth to theRoyal Botanic Garden Edinburgh in 1902 asU. antarctica aurea, and may survive in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. theWentworth Elm).[11] The current list of Living Accessions held in the Gardenper se does not list the plant. In England the tree was supplied by Clibrans' nursery ofAltrincham,Cheshire, asUlmus campestris aurea Rosseelsii.[12][7] Only two specimens are known (2016) to survive in the UK, a stunted tree atBorde Hill, West Sussex.[13] and a small tree (2016) atGrange Farm Arboretum (see Accessions). Others are known in Europe and Australasia[14] (see Accessions).
