The cultivar Ulmus 'Fuente Umbria' was raised from seed collected in 1995 from an elm resembling Ulmus minor growing in a field near Valencia by researchers at the Escuela Técnica Superior de Ingenieros de Montes, Universidad Politėcnica de Madrid. 'Fuente Umbria' is one of seven cultivars 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'. [1]

The leaves, on 10 mm petioles, are ovate, typically oblique at the base and acuminate at the apex, the average length and width 76 × 45 mm, the margins doubly serrate. Foliar density relative to 'Sapporo Autumn Gold' is described as 'medium'. [1]
