Autumn Moon Japanese Maple

Acer shirasawanum 'Autumn Moon'

The Story

Plant Bio

Shirasawa's maple, or fullmoon maple, is a slow-growing Japanese maple species celebrated for its rounded, palmate leaves and elegant structure.

'Autumn Moon' is a stunning cultivar whose chartreuse leaves emerge with reddish-orange tints in spring, holding this color in sun and turning brilliant orange and red in fall.

Uses & Benefits:

Ornamental UsesA premier specimen tree prized for its multi-season display. The foliage emerges with an orange-pink blush over chartreuse, maturing to a bright yellow-green, and culminating in a fiery mix of orange and red in autumn. Its elegant, layered structure is beautiful year-round.
Practical UsesIts small, slow-growing nature makes it a perfect fit for small gardens, courtyards, and large containers. It can be used as a focal point to draw the eye and add a touch of sophistication to any design.
Ecological BenefitsWhile not a major wildlife plant, its dense canopy provides shelter and potential nesting sites for small birds. The leaf litter contributes to rich, organic matter in the soil.
