Acer

Acer plants, commonly known as maples, are grown as much for the way their foliage changes as for the shape of the plant itself. Japanese maples such as Acer palmatum bring finely divided or palm-shaped leaves in green, burgundy, red, gold and variegated tones, often beginning the year in one shade before moving through richer colour as autumn approaches. Upright, spreading and cascading forms give the group a wide range of habits, from compact plants for pots to small trees that gradually become part of the structure of a border.

Placement has a real influence on how a Japanese maple develops. Most prefer a sheltered position in light or partial shade, protected from drying winds and the strongest afternoon sun, which can scorch finer leaves. Fertile, humus-rich soil that stays moist but drains freely suits them well, while many compact Acer varieties are equally at home in a generous container. Red and purple-leaved cultivars can take a little more sun to develop their colour fully, so choosing the right position is often a balance between light, shelter and reliable moisture.

An Acer rewards patience. These are generally slow-growing plants, developing their branching framework and character over many seasons rather than racing to maturity. In spring, fresh foliage gives the first shift in colour, summer brings a settled canopy and autumn can turn the leaves through yellow, orange, crimson or deep red before they fall. With little pruning usually required, Japanese maple trees are well suited to UK courtyards, smaller gardens and containers where that gradual seasonal change can be appreciated year after year.
