The Field Maple Acer campestre cultivar 'Compactum' was first described in 1839.
The tree is mop-headed, the crown a mass of tangled branches. Rarely growing to a height of > 3 m, its leaves are similar in shape but slightly smaller than those of the species.
The tree requires assiduous training to restrain its vigorous growth. As with the species, 'Compactum' thrives best in a semi shade position, on a fertile, well-drained soil.
'Compactum' is also known as Acer campestre 'Nanum'.
