Crimson King Maple Ornamental Tree Description

The Crimson King Maple is a large, deciduous ornamental tree valued for its dramatic foliage and strong landscape presence. As a variety of Acer platanoides, it typically reaches around 12–15 metres in height at maturity, developing a broad, rounded crown that provides structure and shade in spacious gardens.

One of the defining features of the Acer Crimson King is its deep reddish-purple foliage, which emerges in spring and retains much of its rich colour throughout summer.

As autumn approaches, the leaves develop bronze and dark red tones, adding seasonal interest before they fall. Small yellow-green flowers appear in spring, offering a subtle contrast against the dark leaves.

With its dense canopy and distinctive colour, the Crimson King Maple tree works particularly well as a standalone specimen in a lawn or as a feature in a larger landscape.

Its mature size makes it more suitable for gardens with plenty of space than for small or confined planting areas.

Pruning Advice

The Crimson King Maple naturally develops a well-shaped crown and generally needs little pruning once established. Pruning is mainly required to remove dead, damaged or crossing branches and to maintain a healthy branch structure.

Best Time to Prune: Late summer to early autumn is generally suitable for light pruning of Norway maples, helping to reduce excessive sap bleeding.

Maintenance Pruning: Remove dead or damaged branches and any crossing growth that may affect the tree's structure.

Avoid Heavy Pruning: Excessive cutting can spoil the tree's natural shape and reduce its attractive canopy. Avoid unnecessary pruning, particularly during periods of active sap flow.

With occasional maintenance and sufficient growing space, the Crimson King Maple can retain its attractive form without extensive pruning.

Further Information

Distinctive Purple Foliage: The dark maroon leaves provide a strong colour contrast against green shrubs, evergreen planting and lighter-coloured garden features.

Impressive Mature Size: Growing into a large ornamental tree, Crimson King is well suited to spacious gardens, parks and open landscapes where its canopy can develop fully.

Seasonal Interest: Purple-red spring and summer leaves transition into bronze and dark red shades in autumn, creating changing colour throughout the growing season.

Shade and Structure: Its broad, dense crown offers shade and adds height, structure and visual balance to larger outdoor spaces.

Adaptable and Hardy: This Norway maple cultivar tolerates a range of soil conditions and is suited to many UK planting environments, provided the site offers adequate space and suitable drainage.

Frequently Asked Questions

1. How tall does a Crimson King Maple tree grow?

A Crimson King Maple typically reaches around 12–15 metres (40–50 feet) at maturity. Its broad crown also needs sufficient space, making it more suitable for medium to large gardens and open landscapes.

2. Does the Crimson King Maple keep its purple leaves all year?

No. The Crimson King Maple is deciduous, so it loses its leaves in autumn. Its foliage remains deep purple-maroon through much of spring and summer before developing bronze and dark red tones in autumn.

3. Is the Crimson King Maple suitable for a small garden?

The Crimson King Maple is generally not ideal for small gardens due to its mature height and spreading canopy. A more compact ornamental tree may be better suited to a confined space.

4. How far apart should Crimson King Maple trees be planted?

For standalone planting, allow sufficient room for the tree's mature canopy to spread without crowding buildings, paths or other trees. If planting multiple trees, spacing will depend on the desired landscape effect and available space. Avoid placing them too close together.

5. How long does a Crimson King Maple take to reach maturity?

The Crimson King Maple is a moderate-growing tree, typically adding around 30–60 cm per year in suitable conditions. Reaching its mature height of 12–15 metres can take several decades, depending on climate, soil quality and growing conditions.
