Ulmus 'Vanhouttei') is believed to have been first cultivated in Ghent, Belgium circa 1863.[1][2] It was first mentioned by Franz Deegen in 1886.[3] It was once thought a cultivar of English Elm Ulmus minor 'Atinia', though this derivation has long been questioned; W. J. Bean called it "an elm of uncertain status".[4] Its dissimilarity from the type and its Belgian provenance make the 'Atinia' attribution unlikely. Fontaine (1968) considered it probably a form of U. × hollandica.[5] The cultivar is named for the Belgian horticulturist and plant collector Louis Benoit van Houtte, 1810–1876. DescriptionWhen young, the tree has leaves entirely yellow, a colour retained throughout summer. However, as the tree ages, the colouring may begin a gradual reversion to green. A mature specimen which retained its yellow colouration in the crown stood in Edinburgh's Royal Circus Gardens till the early 1990s.[6] The vertically fissured bark of mature trees is unlike that of English elm, with its squarish scaly fissuring. 'Louis van Houtte' has smaller leaves than the not dissimilar Ulmus glabra 'Lutescens' (Golden Wych Elm). Pests and diseases'Louis van Houtte' is vulnerable to Dutch elm disease (DED). Two specimens planted at Kew Gardens in the Pagoda Vista succumbed very rapidly to the earlier strain of DED in 1931.[4] CultivationBefore Dutch elm disease the tree was commonly cultivated in northern Europe.[7][8] The Späth nursery of Berlin marketed it in the late 19th century as U. campestris Louis van Houtte,[9] under which name it was introduced to the Dominion Arboretum, Ottawa, Canada in 1898,[10] and to the Ryston Hall arboretum, Norfolk, UK,[11] (planted 1913).[12] The tree appeared in the 1902 catalogue of the Bobbink and Atkins nursery, Rutherford, New Jersey, as Ulmus aurea Louis van Houtte,[13] and in Kelsey's 1904 catalogue, New York, as U. 'Louis van Houtte'.[14] It is less commonly cultivated in Australasia, where the golden wych elm Ulmus glabra 'Lutescens' has sometimes been mistakenly sold by nurseries under the name 'Louis van Houtte'.[15] Three trees in separate locations are known in the British Isles, [16] a further partial avenue is known in Aberdeen (see {{Section link||Notable trees}}).[18] The cultivar remains in commerce at a nursery in the USA. Notable treesSeveral large trees survive in Sweden, including a specimen in Kristianstad and one, planted c.1890 (girth 3.7 m), in the Serafimerparken, Stockholm (2017).[17][18][19] An old specimen stands in Christchurch Botanic Gardens, Christchurch, New Zealand.[20] Osborne Place, Aberdeen is lined mostly with 'Louis Van Houtte' planted in 1936.[21] Synonymy
