Species Ulmus minor
Cultivar 'Pendula'
Origin Belgium

The Field Elm cultivar Ulmus minor 'Pendula' was said to have been raised in Belgium in 1863.[1] It was listed as Ulmus sativa pendula by C. de Vos in 1887,[2] and by Boom in 1959 as a cultivar.[3]

Henry (1913) distinguished "the true var. pendula", with its "dense crown of foliage", from a cultivar Kew called U. glabra Mill. pendula nova, "a common form of [field elm] with drooping branches".[4][5] The van Houtte Nursery distributed an U. campestris pendula from the 1880s,[6] and the Späth nursery a U. campestris suberosa pendula Hort. in the 1890s.[7]

Krüssman (1984) equated U. minor 'Pendula' with an U. campestris wentworthii, perhaps confusing it with the hybrid Wentworth Weeping Elm.[8]

Description[edit]

The tree has slender pendulous branches,[1] with leaves "smooth and glossy above and strongly glandular beneath, with orange-brown sessile glands".[9] Bean described 'Pendula' as "very vigorous and large-leaved".[10] Green reported that the young twigs are prone to dieback in hard winters.[1]

Henry noted a peculiar feature on outer lower branches of the Kew and Cambridge Botanics specimens – "one or two small supernumerary leaflets at the base of leaves" – a feature visible on Cambridge[11] and Maastricht[12] herbarium specimens. "Other leaves," he added, "are large and broad, as if composed of two ordinary leaves" and "often cleft from apex to base".[4]

Pests and diseases[edit]

'Pendula' is susceptible to Dutch elm disease.

Cultivation[edit]

'Pendula' was included in many European botanical collections in the early 20th C. It is reported from Australasia (see Accessions). It is not known to have been introduced to North America (though a specimen of Späth's U. campestris suberosa pendula was planted in 1899 at the Dominion Arboretum, Ottawa, Canada[13]).

Notable trees[edit]

A tree in the Cambridge University Botanic Garden from the late 19th to mid 20th C,[14] grafted high on English Elm stock and originally listed as U. nitens, was identified as 'Pendula' by Stearn in 1932.[15] It survived the first DED epidemic, its crown removed after dieback in the late 1940s,[16] and had attained a trunk diameter of 3 ft. by 1962, when it was confirmed as U. carpinifolia Gled. var. 'Pendula' by P. F. Yeo.[9] A notable specimen, planted in 1898,[17] stood in the Snouck van Loosenpark, Enkhuizen, The Netherlands (blown down 2015).[18]
