Origin | US |
Ulmus parvifolia 'Zettler' (selling name Heritage)[1] is a Chinese Elm cultivar that is one of three[clarification needed] recent[timeframe?] (< 2006) American introductions selected for their cold hardiness (USA zone 4 tolerant).
Description[]
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.
Pests and diseases[]
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola.[2]
Cultivation[]
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.
