Description
Acer palmatum 'Masu-kagami' Shrub | Japanese maple
A Japanese maple shrub brings a strong ornamental presence to smaller gardens, borders and containers. Acer palmatum 'Masu-kagami' is a deciduous Japanese maple with an upright, bushy and spreading habit. Rather than forming a high tree shape, this shrub develops a rounded, branching silhouette that gives the plant a fuller appearance close to the ground. It reaches approximately 250 cm at maturity. During the growing season, the elegant, hand-shaped leaves are green. In autumn, they change to spectacular shades of red and orange, giving the shrub a clear seasonal highlight. Red and purple flowers appear in May, although flowering is a modest feature compared with the foliage and autumn colour. The plant also produces fruit, but its main value lies in its leaf shape, colour and structured garden form. This Japanese maple shrub suits an ornamental border, a Japanese-style garden or a container where its spreading outline can be appreciated. It benefits from protection against drying winds and strong afternoon sun, as the foliage can be sensitive to drying out. As part of the Acer genus, 'Masu-kagami' is a distinctive choice for gardeners looking for a lower, fuller Japanese fan maple form.
Key features of Japanese maple (Acer palmatum 'Masu-kagami')
- Foliage: The green leaves are elegant and hand-shaped. In autumn, they develop a striking red and orange colour. This seasonal change is the main ornamental attraction of the plant.
- Flowers and growth: Red and purple flowers appear in May, but they are a secondary feature. The shrub form develops an upright, bushy and spreading silhouette, with branching structure close to the ground and a fuller presence than a high-stemmed form.
- Position and shelter: Grow in partial shade or sun, preferably in a sheltered position. Strong afternoon sun and drying winds should be avoided where possible, as the foliage is sensitive to drying out in these conditions.
- Soil: The soil should be humus-rich, well drained and lightly moist. It should retain some moisture without becoming waterlogged. An open, well-aerated structure is important, with an acidic to neutral pH.
- Garden setting: This ornamental shrub works well in a border, a Japanese-style planting or a container. Its defined form also makes it a useful choice within collections of container plants, provided the position offers suitable shelter and moisture.
Uses of Japanese maple shrub in the garden
- Specimen planting: Use Acer palmatum 'Masu-kagami' as a specimen shrub where its hand-shaped foliage and rounded, spreading outline can be seen clearly. The full structure creates a defined focal point without the elevated form of a standard tree.
- Borders and Japanese-style gardens: The shrub fits naturally into an ornamental border or Japanese-style garden. It can be combined with shade-tolerant, moisture-loving ornamental plants and other Japanese-style garden planting to create a calm, structured composition.
- Containers and smaller spaces: This Japanese maple shrub is suitable for container growing and can add height and structure to a patio or other smaller garden area. Its bushy habit gives a strong visual presence without needing a large tree form.
- Hardiness: The plant is hardy to approximately -23.3 to -17.8°C and is listed for USDA zone 6. A sheltered position remains helpful in exposed UK gardens, especially where drying winds can affect the foliage.
- Seasonal value: The strongest ornamental value comes from the green, hand-shaped leaves, the full shrub silhouette and the spectacular red and orange autumn colour. The red and purple May flowers add a modest seasonal detail.
With its upright, bushy and spreading structure, this Acer palmatum 'Masu-kagami' shrub offers a defined ornamental presence in a smaller UK garden, border, Japanese-style setting or container.
