Ulmus pumila, the Siberian elm, is a tree native to Asia.It is also known as the Asiatic elm and dwarf elm, but sometimes miscalled the 'Chinese elm' (Ulmus parvifolia). U. pumila has been widely cultivated throughout Asia, North America, Argentina, and southern Europe, becoming naturalized in many places, notably across much of the United States.
The Siberian elm cultivar Ulmus pumila 'Chinkota' [1] was developed from seed of the cultivar 'Dropmore' by the Horticulture & Forestry Department of South Dakota State University c.1955, [2] as one of a seed-produced line of extremely cold-hardy and drought-resistant trees for use in the Great Plains.
The Siberian elm cultivar Ulmus pumila 'Pinnato-ramosa' was raised by Georg Dieck, as Ulmus pinnato-ramosa, at the National Arboretum, Zöschen, Germany, from seed collected for him circa 1890 in the Ili valley, Turkestan (then a region of the Russian Empire, now part of Kazakhstan) by the lawyer and amateur naturalist Vladislav E. Niedzwiecki while in exile there.
The Siberian Elm cultivar Ulmus pumila 'Pendula' is from northern China, where it is known as Lung chao yü shu (: Dragon's-claw elm). [1] It was classified by Frank Meyer in Fengtai in 1908, [ 2 ] and introduced to the United States by him from the Peking Botanical Garden [ 1 ] as Weeping Chinese Elm . [ 3 ]
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 ...
All four have the Siberian elm U. pumila as a parent, the source of disease-resistance and drought-tolerance genes. 'Morfeo' was released in 2011; it arose from a crossing of the Dutch hybrid clone '405' (female parent) and the Chenmou Elm , the latter a small tree from the provinces of Anhui and Jiangsu in eastern China, The '405' clone is a ...
The good news for the milkvetch plant is that they usually need wildfire to sprout — meaning dormant seeds now have a massive new habitat for a new crop of the rare shrub.
Ulmus pumila, or 'Poort Bulten,' is a Siberian elm cultivar propagated from a tree in Arboretum Poort Bulten in Losser, Netherlands. The original, planted c.1912 by landscape architect Leonard Springer, was included in what was mainly a collection of evergreens, most of which were felled for firewood during World War II.
