Specimen Plant

Acer palmatum 'Royal Garnet', known as the Japanese Maple, brings refined elegance and vibrant colour to any garden. Originating from the renowned Acer family, this deciduous tree is prized for its deeply lobed, wine-red leaves and graceful branching structure.

• Striking Foliage: The palmately lobed leaves emerge rich wine-red in spring and summer before transforming into brilliant orange-red hues each autumn. The delicate, feathery texture adds a lacy look that stands out against green backdrops.
• Growth & Size: Upright in youth, 'Royal Garnet' matures into a rounded crown reaching up to 2m (6.5ft) in height and spreading to 3m (10ft). Its freely branching habit creates a dense yet elegant silhouette—ideal as a specimen tree or in group plantings.
• Garden Impact: This variety excels in containers on patios or as a centrepiece in borders and Japanese-style gardens. Its compact size suits even small spaces while delivering maximum visual impact throughout the year.
