Ornamental Maples for the Garden
Acers Include a Wonderful Variety of Attractive Ornamental Trees
Feb 1, 2009
Acers or maples are a group of 200 different species of ornamental trees and shrubs occurring throughout the northern hemisphere. Most of them are deciduous and many have decorative foliage. The species found in China and Japan are among the most attractive specimens, with deeply cut lobed leaves, and brilliant leaf colours especially in autumn. The genus includes a number of small trees only a few feet in height, making them suitable for the smallest garden, or even for pot-growing, and rivalling in popularity other small ornamental trees like flowering cherries and lilacs.
The British National Collection is held at Westonbirt Arboretum, Tetbury, Gloucestershire, GL8 8QS.

Cultivation
- Plant in moist but well drained neutral or slightly acid soil.
- They will tolerate full sun but most are happiest in part shade – ideally the dappled shade of a larger tree.
- If possible choose a spot sheltered from the wind, as they suffer from wind burn, and a strong wind can carry away the autumn leaves just as they’re at their most colourful.
