| cultivar = 'Atropurpurea' | origin = Späth nursery, Berlin, Germany }} The elm cultivar Ulmus 'Atropurpurea' [:dark purple] was raised from seed at the Späth nursery in Berlin, Germany, circa 1881 as Ulmus montana atropurpurea,[1] and marketed there till the 1930s.[2][3] At Kew it was renamed U. glabra Huds. 'Atropurpurea', but Späth used U. montana both for wych elm and for U. × hollandica hybrids,[4] so his name does not necessarily imply a wych elm cultivar. 'Atropurpurea' was later classed as a cultivar by Boom[5] in Nederlandse Dendrologie 1: 157, 1959.[6] Photographs of an U. glabra 'Atropurpurea' hedge at Wakehurst Place, England, though they show untypical 'coppice' leaves, appear to confirm that Späth's cultivar was synonymous with 'Purpurea', sometimes called U. × hollandica 'Purpurascens'. The Hesse Nursery of Weener, Germany, also marketed U. montana atropurpurea till the 1930s.[7][8] DescriptionHenry described Atropurpurea as having dark purple, folded leaves.[1]Pests and diseases'Atropurpurea' is not known to have any resistance to Dutch elm disease. CultivationOne specimen of U. montana atropurpurea was planted in 1896 at the Dominion Arboretum, Ottawa, Canada.[9] Three supplied by the Späth nursery to the Royal Botanic Garden Edinburgh in 1902 as U. montana atropurpurea may survive in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm);[10] the current list of Living Accessions held in the Garden per se does not list the plant.[11] One planted in 1920 stood in the Ryston Hall arboretum, Norfolk,[12] in the early 20th century.[13] A specimen labelled U. glabra 'Atropurpurea' at Wakehurst Place, England, survives by being treated as a hedging plant, too low to attract the attentions of the Scolytus beetles that act as vectors of Dutch elm disease.
