| Origin | US |
The Chinese Elm cultivar Ulmus parvifolia 'Dynasty' is a United States National Arboretum introduction reputed to be very fast-growing.[1]
Description
A medium tree rarely exceeding 13 m in height, with a spread of similar dimension producing a very rounded shape. Opinions of the tree's aesthetic merit vary; Dirr [2] considered that the tree "borders on a boondoggle" whereas Warren [3] and Jacobson [4] thought the shape 'good', and the foliage a decent autumn colour (the leaves turn orange-yellow).

Pests and diseases
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola.[5] Moreover, the tree's foliage was adjudged "resistant" to Black Spot by the Plant Diagnostic Clinic of the University of Missouri .
Cultivation
The tree is largely limited to North America, although it has been introduced to Italy.
