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.
[1] 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.
