| Origin | US |
The Chinese Elm cultivar Ulmus parvifolia 'Hallelujah' is one of three American introductions made circa 1992 that were selected for their cold hardiness (USA zone 4 tolerant). 'Hallelujah' is known to have withstood -37 °C (-35 °F) in Missouri. The tree was first listed by the Arborvillage Nursery, Holt, Missouri, in its 1993–1994 catalogue.[1]
Description
[edit]The tree is fast growing, to 30 ft. tall and broad in 20 years,[2] ultimately to 50 ft. tall and 60 ft. wide.[3] It is reputed to have very attractive foliage and bark.[1][4] In young trees the bark is shaggy, "with many curling and peeling pieces that reveal a range of brown, cream, and green" beneath. "With age the exfoliation diminishes, exposing a camouflage-colored mottling of gray, cream, orange, brown, and green".[3] The leaves are dark green and leathery.[5]
Pests and diseases
[edit]The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola.[6]
Cultivation
[edit]'Hallelujah' is extremely rare in cultivation beyond North America.
