Origin

The Chinese Elm Ulmus parvifolia Jacq. cultivar 'Emer I' or 'Emerald Isle' (Athena™) is a small tree rarely exceeding 6 m in height, with a slightly broader, dense and rounded crown. The leaves are a medium, glossy green, turning yellow in autumn. The exfoliating, mottled bark is considered very attractive. The tree featured in the elm trials[1] conducted by Northern Arizona University at Holbrook, Arizona, but was unsuited to the hot, arid climate and sustained over 50 % mortality in its first year. The tree is currently being evaluated in the National Elm Trial [2] coordinated by Colorado State University.

'Emer 1' was cloned from a tree planted circa 1920 on the University of Georgia campus at Athens ^[1]. The tree was introduced to Australia in 2002 as part of the Australian Urban Street Planting Programme [3]; it is not known to have been introduced to Europe.
