| Hybrid parentage | U. glabra × U. minor |
| Cultivar | 'Cinerea' |
| Origin | Europe |
The hybrid elm cultivar Ulmus × hollandica 'Cinerea' was first listed by George Lindley (father of John Lindley) in 1815, and later by the Andre Leroy Nurseries, Angers, France, in 1856 as Ulmus cinerea. A specimen in cultivation at Kew in 1964 was found to be U. × hollandica, but the tree at Wakehurst Place remains listed as U. glabra 'Cinerea'.[1]
Description
The tree was described as having branches "stunted and tortuous, the upper ascending, the lower more or less pendulous". [2]
Pests and diseases
The tree is susceptible to Dutch elm disease.
Cultivation
Only one living specimen is known, at Wakehurst Place, England, where it survives by being treated as a hedging plant, too low to attract the attentions of the Scolytus beetles that act as vectors of Dutch elm disease. 'Cinerea' is not known to have been introduced to North America or Australasia.
