- Ulmus americana 'Pendula'
Infobox Cultivar | name = "Ulmus americana"
cultivar = 'Pendula'
origin = EnglandThe American Elm "Ulmus americana" 'Pendula' is considered probably just a "forma" by Green, although it was originally listed by William Aiton in "Hort. Kew", 1: 320, 1789 as "U. americana" var. "pendula", cloned in England in 1752.
Description
The tree was described as vase-shaped with branches pendulous at their extremities [Green, P. S. (1964). Registration of cultivar names in Ulmus. "Arnoldia", Vol. 24. Arnold Arboretum, Harvard University. [http://arnoldia.arboretum.harvard.edu/pdf/articles/1605.pdf] ] . ]Cultivation
The tree was not known to have been cultivated beyond the UK, where only one specimen is known to survive, and the Netherlands.
Hybrid cultivars
'Pendula' was used in the Dutch elm breeding programme before World War II, but none of the progeny were of particular note and are not known to have been cultivated [Went, J. C. (1954). The Dutch elm disease - Summary of 15 years' hybridisation and selection work (1937-1952). "European Journal of Plant Pathology", Vol 60, 2, March 1954.] NB: 'Pendula' was later confused with a pendulous variant of "U. glabra".]ynonymy
