Cultivar'Argenteo-Marginata'
OriginGermany

The elm cultivar Ulmus 'Argenteo-Marginata' was first mentioned by Deegen in Deutsches Magazin für Garten- und Blumenkund (1879),[1] as Ulmus campestris elegans foliis argenteo-marginatis. An U. campestris fol. argenteo-marginata Hort. (later just U. campestris argenteo-marginata) was distributed by the Späth nursery, Berlin, from the 1890s to the 1930s.[2][3]

Green considered the tree possibly a cultivar of Field Elm or of U. × hollandica.

Description

Deegen described the tree as having leaves bordered with white. The leaves were described in a later reference as also being very rough above, weakly pubescent below, and measuring < 8 cm long by < 4 cm broad.[4] Späth catalogues likewise describe white-bordered leaves.[2][3]

Cultivation

No specimens are known to survive, unless the tree is synonymous with one of two cultivars with sometimes silver-white margined leaves, U. minor 'Argenteo-Variegata' or the rough-leafed U. minor 'Atinia Variegata',[5] both of which match the microphylla foliis marginatis description (Synonymy below). One tree was planted in 1897 as U. campestris fol. argenteis marginatis at the Dominion Arboretum, Ottawa, Canada.[6] Three specimens supplied by the Späth nursery, Berlin, to the RBGE in 1902 as U. campestris fol. argenteo-marginata may survive in Edinburgh, as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm);[7] the current list of Living Accessions held in the Garden per se does not list the plant.[8]
