Origin
USA

The Chinese Elm Ulmus parvifolia Jacq. cultivar 'Emer II' or 'Emerald Vase' (Allee™) can reach a height of about 15 m, with a spread of approximately 13 m. Its shape is upright, vase with arching branches bearing medium green, glossy leaves turning orange to rust red in autumn. The exfoliating, mottled bark has a puzzle-like pattern, and is considered outstandingly attractive ^[1]. The tree is reputedly drought tolerant, but in the elm trials [1] conducted by Northern Arizona University at Holbrook, Arizona, 'Emer II' (Allee™) proved unsuited to the hot, arid climate and sustained over 50% mortality in its first year, as did its sibling 'Emer I' (Athena™). The tree is currently being evaluated in the National Elm Trial [2] coordinated by Colorado State University.

'Emer II' (Allee™) was cloned from a tree planted circa 1910 on the University of Georgia campus at Athens. It is not known to have been introduced to Europe or Australasia.
