A group of clones derived by crossing 'Italica' with P. nigra ssp betulifolia at the Plantières Nursery near Metz in France in 1884; they are similar to 'Italica' (and often mistaken for it) but with a slightly broader crown, and better adapted to the cool, humid climate of northwest Europe, where the true Lombardy poplar does not grow well.
Un grupo de clons obtidos por cruzamento 'Italica' con P. nigra ssp betulifolia no viveiro de ‘’Plantières’’ preto de Metz en Francia en 1884; son semellantes a 'Italica' (e, a miúdo se confunden con ela) porén teñen a copa lixeiramente máis ampla e mellor axeitada ao clima frío e húmido no noroeste de Europa, onde o verdadeiro chopo lombardo non crece ben.
