| Origin | Belgium |
The hybrid elm cultivar Ulmus × hollandica 'Dumont' was a very vigorous elm raised from a tree discovered by a gardener on the estate of M. Dumont at Tournay, Belgium, c. 1865.[1]
Description
The tree had a straight trunk and a narrow regular, pyramidal crown, Elwes likening it to Wheatley Elm in habit.[2] The leaves were somewhat smaller than those of 'Belgica'.[3][4]
Pests and diseases
'Dumont' was very susceptible to Dutch elm disease.
Cultivation
No specimens are known to survive. The tree was once a popular choice for street planting in Belgium and France, notably at Ypres, where Henry collected a specimen for Kew Gardens in 1912,[5] and at Versailles (town, not palace), where it was supplied by Moser's nursery and planted in "peculiar clipped avenues".[2] Early 20th-century photographs of the Place Barascude and Avenue Thiers, Versailles, show Wheatley-like elms, some clipped, and pruned avenues by Moser's nursery.[6][7] An U. campestris Dumont, "a vigorous grower" with "large leaves", appeared in the 1909 catalogue of the Bobbink and Atkins nursery, Rutherford, New Jersey.[8] The Hesse Nursery of Weener, Germany, marketed an Ulmus latifolia Dumont in the 1930s.[9]
