| Origin | Spain |
The field elm cultivar Ulmus minor 'Ademuz' was cloned by root cuttings from a tree assumed to be growing in or near the eponymous town 100 km north-west of Valencia,[1] Spain. The tree was discovered in 1996 by Margarita Burón of the Escuela Técnica Superior de Ingenieros de Montes, Universidad Politėcnica de Madrid (UPM). 'Ademuz' is one of a number of U. minor clones found to have a very high resistance to Dutch Elm Disease, on a par with, if not greater than, the hybrid cultivar 'Sapporo Autumn Gold' grown as a control. In the Madrid study, the appearance of the tree was rated 4.5 / 5, the most attractive of the seven selected cultivars.[1]
Propagation of 'Ademuz' is protected by an EU Grant of Rights, given on 02/07/2018 under Grant ref. 49920.
'Ademuz' was introduced to the UK in 2014, by Hampshire & Isle of Wight Branch, Butterfly Conservation, as part of an assessment of DED-resistant cultivars as potential hosts of the endangered White-letter Hairstreak.[2][3]
