The Weeping Wych Elm, also known as the Horizontal Elm Ulmus glabra 'Horizontalis' is an elm cultivar with branches that extend out horizontally with weeping branchlets. It is usually grafted onto a tall understock of Ulmus glabra to effectively display its weeping habit. It can eventually grow to a height of 20 metres with a similar spread [1].
The cultivar was discovered in a Perth nursery circa 1816, but first distributed in Germany by Booth of Hamburg, who bought the entire Perth stock. It was also known to have been marketed in Poland in the 19th century by the Ulrich nursery [2], Warsaw.
The tree was originally identified as 'Pendula' by Loddiges (London), in his catalogue of 1836, a name adopted by Loudon two years later in Arb. Frut. Brit 3: 1398, but later sunk as a synonym for 'Horizontalis' [3]. It can be distinguished from the related Camperdown Elm by its more spreading and flattened canopy and much larger mature size, although its shape does vary widely, as noted by Loudon: "A beautiful...tree generally growing to one side, spreading its branches out in a fan-like manner...sometimes horizontally and and at other times almost perpendicularly downwards so that the head of the tree exhibits great variety of shape" [4].
Introduced to Australia, the cultivar can be observed in a number of public gardens in Victoria.
