Acer platanoides 'Globosum'Norway maple

Acer platanoides ‘Globosum’ is usually grafted onto a straight stem, often at a height of about 2 to 2.2 metres. From that point it develops a compact, spherical crown, which becomes broader and slightly flattened with maturity. It can reach approximately 5 to 7 metres in height and a similar spread, although old specimens may develop more expansive crowns.

The height of the stem remains essentially fixed by the graft union, while the crown gradually increases in volume. This makes it possible to predict more accurately the relationship between the tree, the paths and the built elements, which makes it particularly useful in projects with a regular geometry.

The palmate leaves open with a slight reddish-brown tint and turn dark green during the summer. In spring, small greenish-yellow flowers appear before the leaves, followed by the winged samaras characteristic of maples. In autumn, the crown takes on an intense, uniform golden-yellow colour.

It adapts to sun or partial shade and to different soil types, provided drainage is adequate. It has good resistance to cold, to wind, to periods of drought once established and to urban conditions. The progressive spread of the crown favours its use in squares, pedestrian areas, car parks, entrances and small or medium-sized gardens with sufficient lateral space.

With a mature specimen from Diaplant, the stem height, the crown diameter and the regularity of the form can be assessed before selection. This makes it possible to bring shade, scale and geometric repetition to the project immediately, creating avenue plantings or sequences of uniform crowns without waiting several years for the cultivar’s characteristic form to develop.
