Ulmus parvifolia 'Emer I'
The Chinese Elm cultivar Ulmus parvifolia 'Emer I' or 'Emerald Isle' (trade designation: Athena) was cloned from a tree planted circa 1920 on the University of Georgia campus at Athens.[1] DescriptionAthena is a small tree rarely exceeding 6 m in height, with a slightly broader, dense and rounded crown.[2] The leaves are a medium, glossy green, turning drab brown in autumn. The exfoliating, mottled bark is considered very attractive.[3] Pests and diseasesThe species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola.[4] As with the species overall, damage caused by Japanese Beetle is relatively slight.[5] CultivationAthena 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. It is currently being evaluated in the National Elm Trial [2] coordinated by Colorado State University. Athena 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. Synonymy
