Ulmus 'Variegata' (Smooth-leafed Elm Cultivar)
The Field Elm cultivar ''Ulmus minor'' 'Argenteo-Variegata' or simply 'Variegata', known in Australasia and North America as Silver Elm or Tartan Elm, is said to have been cultivated in France from 1772. Green noted that variegated forms of Field Elm "arise frequently, and several clones may have been known under this name". Dumont de Courset (1802) listed an ''U. campestris'' var. ''glabra variegata'', Loudon (1838) an ''U. nitens'' var. ''variegata'', and Wesmael (1863) an ''U. campestris'' var. ''nuda microphylla variegata''. 'Variegata' is not to be confused with the variegated English Elm cultivar, ''U. minor'' 'Atinia Variegata', which has the broader, almost orbicular leaves of the type. Description The tree's foliage is randomly blotched and speckled with creamy white, the colour of the leaves on the same tree ranging from almost completely cream to totally green.''Hilliers' Manual of Trees & Shrubs''.

Ulmus Minor
''Ulmus minor'' Mill., the field elm, is by far the most polymorphic of the European species, although its taxonomy remains a matter of contention. Its natural range is predominantly south European, extending to Asia Minor and Iran; its northern outposts are the Baltic islands of Öland and Gotland, although it may have been introduced by humans. The tree's typical habitat is low-lying forest along the main rivers, growing in association with oak and ash, where it tolerates summer floods as well as droughts.Heybroek, H. M., Goudzwaard, L, Kaljee, H. (2009). ''Iep of olm, karakterboom van de Lage Landen'' (:Elm, a tree with character of the Low Countries). KNNV, Uitgeverij. Current treatment of the species owes much to Richens, who noted (1983) that several varieties of field elm are distinguishable on the European mainland. Of these, he listed the small-leaved ''U. minor'' of France and Spain; the narrow-leaved ''U. minor'' of northern and central Italy; the densely hairy leaved ...

Dutch Elm Disease
Dutch elm disease (DED) is caused by a member of the sac fungi (Ascomycota) affecting elm trees, and is spread by elm bark beetles. Although believed to be originally native to Asia, the disease was accidentally introduced into Americas, America, Europe, and New Zealand. In these regions it has devastated native populations of elms that did not have resistance to the disease. The name "Dutch elm disease" refers to its identification in 1921 and later in the Netherlands by Dutch phytopathologists Marie Beatrice Schol-Schwarz, Bea Schwarz and Christine Buisman, who both worked with professor Johanna Westerdijk. The disease affects species in the genera ''Ulmus'' and ''Zelkova''; therefore it is not specific to the Ulmus × hollandica, Dutch elm hybrid. Overview Dutch elm disease (DED) is caused by ascomycete microfungi. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years.

In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Dominion Arboretum
The Dominion Arboretum (french: Arboretum du Dominion) is an arboretum part of the Central Experimental Farm of Agriculture and Agri-Food Canada in Ottawa, Ontario, Canada. Originally begun in 1889, the Arboretum covers about of rolling land between Prince of Wales Drive, Dow's Lake and the Rideau Canal. Carleton University is located at the opposite side of the Canal. At a latitude of 45°, it can experience extremely hot and humid summers and extremely cold winters.

Späth Nursery
The Späth (often spelt ''Spaeth'') family created one of the world's most notable plant nurseries of the 19th and early 20th centuries. The nursery had been founded in 1720 by Christoph Späth but removed to the erstwhile district of Baumschulenweg (lit. 'nursery way'; now part of the Treptow-Köpenick district) in south-east Berlin in 1863 when Franz Ludwig Späth (1839 - 1913) succeeded his father Ludwig as manager when aged only 25. By the end of the 19th century, the nursery was the largest in the world, occupying 120 hectares. In 1874 Franz built a mansion on the site, now part of Humboldt University and, five years later, established an arboretum. After his death in Britz in 1913, Franz Späth was succeeded by his son, Hellmut, who revived the nursery's flagging fortunes during the Depression by joining the Nazi Party and securing lucrative landscaping contracts for the new autobahns and other public works. However, his outspoken criticism of the Nazi regime saw him i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
