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.
The tree was described as "a strongly weeping little plant growing perhaps after many years". A specimen at the Arborvillage Nursery was less than after 3 years.
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the elm leaf beetle Xanthogaleruca luteola.
Restricted to North America; the only known introduction to Europe, is at the Grange Farm Arboretum, England.
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.
