Lobel (elm hybrid)

From Wikipedia, the free encyclopedia

A Dutch hybrid elm raised at Wageningen, Lobel was cloned in 1962 and released for sale in 1973. Derived from a crossing of clone 202 (U. glabra Exoniensis x U. wallichiana) with 336 (U. minor Bea Schwarz, selfed), Lobel is a fastigiate, small-crowned, small-leaved tree not unlike the pyramidal Hornbeam Carpinus betulus Fastigiata. It has proven resistant to sea winds, and was accordingly planted in large numbers by Portsmouth City Council in the late 1980s but has not proved more than marginally resistant to Dutch elm disease and consequently planting is no longer recommended.

Lobel is not known in the USA. It was included in trials [1] in Canberra, Australia started in 1988, but has not thrived in that environment. The tree is named for Matthias de L'obel, the Flemish botanist also commemorated by the genus Lobelia.
