Cultivar
'Pendula'
Origin
England

The 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. It was described as vase-shaped with branches pendulous at their extremities ^[1]. This tree was later confused with a pendulous variant of U. glabra.
