- Description

Acer japonicum, has rounded leaves which look much like a full moon, hence the common name. It is a deciduous, spreading, small tree or large shrub with smooth, gray bark that grows up to 20-30’ tall. It often grows in a multi-trunked form. It is native to mountainous areas of Japan, Manchuria, and Korea. Leaves turn yellow and red in fall. Small purplish-red flowers in pendulous corymbs appear in early spring (April) before the leaves.
Plants prefer cool summer conditions with lightly dappled shade. Site in locations protected from strong winds. Stake young trees for more erect growth. Plants perform poorly south of USDA Zone 7. Leaves may scorch in full sun in hot southern summers.
Site: Sun to partial shade; prefers moist, well-drained soil but is adaptable
Texture: Medium to fine
Form: Upright; multi-branching; sturdy, stiff twigs; rounded top
