An excellent, medium sized deciduous tree. Very useful urban tree where an adaptable but ornamentally attractive tree is required. Tolerates enclosed, confined root spaces. Bark is thin and can be easily damaged by mechanical injury. Transplants easily with moderate to fast growth rate.

Cultivar. Dark glossy leaves, drought resistance, orange to red fall colour and a smaller ultimate size are inherited from Shantung Maple (Acer truncatum). The Norway parent (Acer platanoides) contributes faster growth, calliper development at an early age, larger leaves and adaptability to varied growing conditions.

Medium deciduous tree with a narrow upright form while young developing to a broad domed crown. Its fine textured branch structure evolves to a rounded crown and a mature height of about 10-12 m x 7-10 m wide.

Leaves palmate, glossy, dark green turning yellow to scarlet in autumn. Thick bark, grey-black, becoming lightly ridged and furrowed with age. Flowers are green, inconspicuous, borne in panicles.

Tolerates a wide range of soil conditions including both slightly alkaline and acid soils. Tolerant of drought and air pollution. Grows well in limited soil space in urban areas. Transplants easily, and is generally free of any serious pests or diseases.
