发明名称 Japanese elm tree named 'Discovery'
摘要 A new cultivar of Japanese elm tree (ie., Ulmus davidiana Japonica) is provided that exhibits excellent form and resistance to Dutch elm disease. Unlike other Japanese elm trees the growth habit is clean, symmetrical, upright, and vase-shaped. The foliage is obovate to oval in configuration and is slightly smaller than is typical for the species. Good cold hardiness and resistance to elm leaf beetles are exhibited. The new cultivar is particularly suited for growing as an attractive landscape shade tree.
