|---|---|
| Species | Ulmus glabra |
| Cultivar | 'Tomentosa' |
| Origin | Europe |
The Wych Elm cultivar Ulmus glabra 'Tomentosa' was first listed as Ulmus tomentosa by Kirchner in Arboretum Muscaviense (1864).[1] The Hesse Nursery of Weener, Germany , distributed an Ulmus montana tomentosa in the 1930s.[2] Green listed it as a wych elm cultivar.[3]
Description
The tree was later described as having the undersides of the leaves covered with thick, soft hairs, giving a pronounced grey-green appearance.[3]
Cultivation
A 'Tomentosa' is listed in the Red Data Book of the Baltic Region (1993),[4] suggesting that the cultivar may still survive there. It is not known to be in cultivation elsewhere.
