| Wageningen, The Netherlands |
A Dutch hybrid cultivar raised at Wageningen, 'Lobel' was cloned in 1962 and released for sale in 1973. Derived from a crossing of clone 202 (U. glabra 'Exoniensis' × U. wallichiana) with 336 (U. 'Bea Schwarz', selfed), 'Lobel' is a fastigiate, small-crowned, small-leaved tree not unlike the pyramidal Hornbeam Carpinus betulus 'Fastigiata'.[1][2]. The tree is notably late to flush, its leaves rarely developed before mid-May [3]. Like its Dutch contemporaries 'Dodoens' and 'Plantyn' 'Lobel' has proven no more than marginally resistant to Dutch elm disease, and sales in the Netherlands declined from over 12,000 in 1989 to 1,100 in 2004[4] [1]. Planting is no longer recommended wherever the disease is prevalent.[5]
'Lobel' is particularly resistant to sea winds, and was accordingly planted in large numbers by Portsmouth City Council in the late 1980s, notably to replace the ancient Huntingdon Elms lost in the Great Storm of 1987 along the Ladies' Mile on Southsea Common. There are also large plantings at Ealing and Primrose Hill, London, Brighton & Hove, and Havant. 'Lobel' was included in trials [2] in Canberra, Australia started in 1988 but has not thrived in that environment. It is not known to have been commercially released in North America, although it was evaluated at the Iowa State University in the 1970s[6] and may still survive there.
