Fiorente is an elm cultivar derived from a crossing of the Siberian Elm U. pumila clone S 10 with U. minor C. 02 by the Istituto per la Protezione delle Piante (IPP) in Florence, Italy, and released for sale in 2007. Fiorente is monocormic, and of exceptionally rapid growth on fertile soil in a temperate climate, bestowing it a potential economic importance as a timber tree. Mean growth during trials in the Northern Apennine exceeded one metre in height and 1.5 cm in trunk diameter per annum. The tree's habit is conical, with a pronounced apical dominance. The lateral growth on the current year's growth is very limited; the crown is therefore rather columnar. The alternate leaves are of a moderate size, < 8 cm long by < 5 cm broad. Generally lanceolate in shape, the leaves are rough on the upper surface and pubescent beneath; they remain green well into the autumn and are shed relatively late. The tree usually commences flowering in its fourth or fifth year, and has proved highly resistant to Dutch Elm Disease when inoculated with the Ophiostoma fungus.
