Acer negundo - Maple

Acer negundo, also known as box elder maple, is a tree with tender green compound foliage, producing thick clusters of yellow-green or red flowers.

Originally from the United States, this 15m (49ft) tall tree is perfectly hardy. It has a spreading habit, with thin and fragile branches. The compound deciduous leaves, with 3 or 9 ovate leaflets, are light green. In June, thick and pendulous clusters of green-yellow female flowers and red male flowers bloom, before giving way to winged fruits 3 to 5cm (1 to 2in) long.

Easy to grow, the box elder maple thrives in any moist, fertile, well-worked and well-drained soil, in a sunny or partly shaded location. Find a spot sheltered from strong winds.

Acer negundo has rapid growth. It is ideal at the base of large trees to create an intermediate vegetal screen.

Tips: Prune every 3 to 5 years to balance the branches and maintain a harmonious habit.
