![]() 'Dwarf Weeper', Grange Farm Arboretum | |
Species | Ulmus pumila |
Cultivar | 'Dwarf Weeper' |
Origin | US |
The Siberian Elm cultivar Ulmus pumila 'Dwarf Weeper' was discovered in a western Illinois garden and sold by the Arborvillage Nursery (ceased trading in 2006) Holt, Missouri.[1]
Description
The tree was described as "a strongly weeping little plant growing 7 ft (2.1 m) perhaps after many years".[1] A specimen at the Arborvillage Nursery was less than 3 ft (0.91 m) after 3 years.[1]
Pests and diseases
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola.[2]
Cultivation
Restricted to North America; the only known introduction to Europe, is at the Grange Farm Arboretum, England.
Putative specimen
A notably pendulous small-leaved elm in the JC Raulston Arboretum, Raleigh, North Carolina (2019), labelled Ulmus minor subsp. minor 'Pendula', 'Weeping small-leaved elm', has U. pumila-type fruit and is indistinguishable in leaf and form from U. pumila 'Dwarf Weeper'. The arboretum acquired other specimen trees from Arborvillage Nursery, Holt, Missouri.[3]
