Origin | US |
The Chinese Elm cultivar Ulmus parvifolia 'Sempervirens' is an American introduction from south China, [1] commonly known by the synonym 'Evergreen'. It was first listed by Bailey & Bailey in Hortus Second, 747, 1941. [2]
Semi-evergreen to evergreen depending on climate, it is described as having a rounded crown and gracefully arching branches bearing deep-green foliage.
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola . [3]
The tree remains in commercial cultivation in the USA. Wilkinson states that it was cultivated in Florida. [1] It is not known to be in cultivation in Europe or Australasia.
