This old cultivar forms a small-leaved, regular, ball shaped shrub. It comes from the UK and was named by Loudon in 1839, introduced by De Vos in the Netherlands in 1895 (MOW). Called 'Globosum' by Bean, it stands strong sun and is drought resistant. A very useful maple for small gardens, or as an accent plant. I forgot to mention, Nanum is sometimes sold as a solitaire (high graft). In this case it makes a perfect and surreal lollipop shape. Since Field Maples take so well to cutting, I imagine it could be formed into cubes or whatever. It would be fun to make a formal alley with a head high, long cubic rectangle of maple on each side!
