Ulmus Americana 'Pendula'
The American elm cultivar ''Ulmus americana'' 'Pendula' was originally listed by William Aiton in ''Hort. Kew'', 1: 320, 1789, as ''U. americana'' var. ''pendula'', cloned in England in 1752 by James Gordon. From the 1880s the Späth nursery of Berlin supplied a cultivar at first listed as ''Ulmus fulva'' (Michx.) ''pendula'' Hort., which in their 1899 catalogue was queried as a possible variety of ''U. americana'', and which thereafter appeared in their early 20th-century catalogues as ''U. americana pendula'' (formerly ''Ulmus fulva'' (Michx.) ''pendula'' Hort.).Späth nursery, Catalogue 143, p. 135, 1910–11. Berlin, Germany. The Scampston Elm, ''Ulmus'' × ''hollandica'' 'Scampstoniensis', in cultivation on both sides of the Atlantic in the 19th and 20th centuries, was occasionally referred to as 'American Weeping Elm' or ''Ulmus americana pendula''. This cultivar, however, was distinguished by Späth from his ''Ulmus americana pendula''. 'Pendula' was consider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulmus Americana
''Ulmus americana'', generally known as the American elm or, less commonly, as the white elm or water elm, is a species of elm native to eastern North America, naturally occurring from Nova Scotia west to Alberta and Montana, and south to Florida and central Texas. The American elm is an extremely hardy tree that can withstand winter temperatures as low as −42 ° C (−44 ° F). Trees in areas unaffected by Dutch elm disease (DED) can live for several hundred years. A prime example of the species was the Sauble Elm, which grew beside the banks of the Sauble River in Ontario, Canada, to a height of 43 m (140 ft), with a d.b.h of 196 cm (6.43 ft) before succumbing to DED; when it was felled in 1968, a tree-ring count established that it had germinated in 1701. For over 80 years, ''U. americana'' had been identified as a tetraploid, i.e. having double the usual number of chromosomes, making it unique within the genus. However, a study published in 2011 by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
