Ulmus 'Morton'
''Ulmus'' 'Morton' (selling name ) is an elm cultivar cloned from a putative intraspecific Hybrid (biology), hybrid planted at the Morton Arboretum in 1924, which itself originated as seed collected from a tree at the Arnold Arboretum in Massachusetts. Although this tree was originally identified as ''Ulmus crassifolia'', it is now believed to have been a hybrid of the Japanese elm (Ulmus davidiana var. japonica, ''Ulmus davidiana'' var. ''japonica'') and Wilson's elm (formerly ''Ulmus wilsoniana'', but also sunk as ''U. davidiana'' var. ''japonica''). has proven to be the most successful cultivar tested in the US National Elm Trial, averaging a survival rate of 92.5% overall. Description The parent tree at the Morton Arboretum is noted for the resemblance of its habit to the American elm ''Ulmus americana'', its upright-arching branches creating the familiar vase-shape, although the tree does not grow as large as the iconic native elm, reaching scarcely 20 m at maturity. ...
