hybrid cultivar raised at Wageningen, Ulmus Lobel was derived
from a crossing of clone 202 (U. glabra 'Exoniensis' ×
with 336 ('Bea Schwarz'
selfed), cloned in 1962 and released for sale in 1973.
'Lobel' is a fastigiate, small-crowned, tree not unlike the
pyramidal Hornbeam Carpinus
'Fastigiata'.Heybroek, H. M. (1983). Resistant

Following the development and release of cultivars such as 'Columella'
more resistant to Dutch elm disease
, planting is no longer
recommended wherever the disease is prevalent. Sales in the Netherlands declined from over 12,000 in 1989 to 1,100 in 2004
. However, '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.
was included in trials  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 and may still survive there.
