Ulmus parvifolia 'Zettler' (selling name Heritage)[1] is a Chinese Elmcultivar that is one of three[clarification needed] recent[timeframe?] (< 2006) American introductions selected for their cold hardiness (USA zone 4 tolerant).
Heritage 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 selected from over 20,000 seedlings in 1975, and subsequently proved to be one of the hardiest Chinese or Lacebark Elms available in the United States, surviving −33 °C (−27 °F) in Illinois during the winter of 1989 without sustaining any damage whatsoever. Heritage is not known to have been introduced to Europe or Australasia.
