| Origin | England |
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.[1][2]
'Pendula' was later confused with a pendulous variant of an Ulmus glabra (see 'Synonymy'). The Scampston Elm, Ulmus × hollandica 'Scampstoniensis', in cultivation on both sides of the Atlantic in the 19th and 20th centuries, was occasionally referred to as 'American Weeping Elm' or Ulmus americana pendula.[3][4]
Description
The tree was described as vase-shaped with branches pendulous at their extremities.[1]
Cultivation
'Pendula' is only known to have been cultivated in the UK (most recently in Ayrshire[5]) 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 [6]
Synonymy
