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 × 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.
