Acer japonicum Fullmoon Maple1

Edward F. Gilman2

Introduction

Full-moon maple is a small, deciduous tree that reaches 10 to 15 feet in both height and width, creating a smooth, rounded canopy (Figure 1). It fits well into the oriental garden due to its exotic silhouette. The cultivar 'Acontifolium' is exceptionally cold hardy, having survived temperatures of 25°F below zero. The deeply divided, soft green leaves have 9 to 11 lobes and are delicately displayed on thin, drooping branches. The cultivar 'Vitifolium's' leaves are less divided, providing a coarse texture in the landscape. Leaves take on a beautiful yellow to red coloration in the fall before dropping, making this small, dense plant really stand out in the landscape. Fall color has been described as exceptional. The hanging clusters of showy, purple/red flowers appear in late spring and are followed by the production of winged seeds. The full-moon maple's flowers stand out among the maples.

Use and Management

This maple is well-suited for the residential landscape as well as the commercial setting. Planted near a patio or deck, it will generate many comments from friends and other visitors. It is probably best used as a specimen, planted to attract attention to an area. It should live for at least 20 years. Nice specimens can be viewed at arboreta, but few nurseries currently offer these cultivars for sale. This may change as nursery operators and homeowners discover the trees.

Full-moon maple can be grown in sun to almost full shade. Nice specimens can be seen growing in the filtered shade of tall, overstory trees, or where there is 2 to 6 hours of direct sun shining on the plant. Where the sunlight is intense, the tree will benefit from having its roots shaded or mulched to help keep the soil cool. A generous helping of mulch out to the edge of the canopy is beneficial.

Pests and Diseases

None of major concern except for verticillium wilt.
