The Chinese Elm U. parvifolia cultivar Zettler (Heritage™) [1] is one of three recent (< 2006) American introductions selected for their cold hardiness (USA zone 4 tolerant). The tree has a strong, upright habit and excellent branching structure, bearing deep green glossy foliage that turns to an attractive autumn colour in some years. Heritage™ was originally selected from over 20,000 seedlings in 1975, and subsequently proved to be one of the hardiest Chinese or Lacebark Elms available in the USA, surviving -28° F (-33° C) in Illinois during the winter of 1989 without sustaining any damage whatsoever.
