The Chinese elm cultivar Ulmus parvifolia 'Sempervirens' is an American introduction from south China, commonly known by the synonym 'Evergreen'. It was first listed by Bailey & Bailey in Hortus Second, 747, 1941.
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.
The tree remains in commercial cultivation in the USA. Wilkinson states that it was cultivated in Florida. It is not known to be in cultivation in Europe or Australasia.
