But it was precisely in Europe that it is believed to have given rise, through a spontaneous crossing with Platanus orientalis, to the much more important Platanus acerifolia.
Its limited use is due to the fact that both the Oriental and the hybrid Platano have better characteristics both at an ornamental and a technological level.
