The American Elm cultivar 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 by James Gordon.
Contents
NB: 'Pendula' was later confused with a pendulous variant of U. glabra.
Description
The tree was described as vase-shaped with branches pendulous at their extremities.
Pests and diseases
The clone's resistance to Dutch Elm Disease is not known, but the species is highly susceptible to the disease and Elm Yellows; it is also moderately preferred for feeding and reproduction by the adult Elm Leaf Beetle Xanthogaleruca luteola [1], and highly preferred for feeding by the Japanese Beetle Popillia japonica [2] [3] in the United States. U. americana is also the most susceptible of all the elms to verticillium wilt.
Cultivation
'Pendula' is only known to have been cultivated in the UK and the Netherlands; no surviving (2016) trees have been confirmed.
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
