The cultivar 'Nanum' is a very conspicuous cultivar that catches the attention because of its very dense, bulbous crown. A crown that can reach circa 3 m both in height and spread. Because of this crown the 'Nanum' can easily be applied in shopping areas, on parking lots and in (town) parks. In autumn the tree has an extra decorative value because the leaves turn into a beautiful dark yellow autumn colour. The plant has to be propagated by grafting and the height of the stem depends strongly on the height of the grafting. A graft height of 2.2 m is usual. This plant is also grown as a shrub. The height of grafting is not relevant then. As a shrub 'Nanum' assumes the same shape: dense and bulbous.
