Acer griseum: Paperbark Maple1

Edward F. Gilman and Dennis G. Watson2

Introduction

Perhaps the most beautiful maple, paperbark maple has trifoliate leaves and wonderfully orange to bronze, peeling, papery bark which provides year round interest. The bark begins peeling on the sculptured trunk and on 2-or 3-year-old branches. It may be cinnamon brown or orange but is usually a dark reddish-brown, looking particularly striking in the snow. Even small branches display exfoliating bark making this a true specimen tree, even at a young age. Most specimens are seen with multiple trunks which branch close to the ground, but proper training when young can create a single trunk. Paperbark maple has vibrant, scarlet, autumn foliage.

Use and Management

The multi-stemmed habit, unusual leaves, and wonderful bark makes this a prime candidate for specimen planting in any commercial, institutional, or residential landscape. If you can find it, plant it by a patio or other prime location and light it from below for nighttime enjoyment.

The tree is hardy, grows very slowly to 25 or 30 feet tall, but, unfortunately, is difficult and expensive to propagate. It does not tolerate extended drought or other environmental stresses in the south or in poor soil (moderate drought-tolerance in sandy loam) but will grow in sun or shade. Leaves will scorch during dry summers unless provided with some irrigation. Probably best in partial shade if planted in the south. The beauty of this tree makes up for the extra effort required to grow it. If this plant could be easily propagated, it would be widely used because the price of the plant would drop to levels acceptable to most people.

Pests and Diseases

Probably has similar pest and disease problems as other maples.
