Roots & heritage
Autumn Moon is accepted by the Royal Horticultural Society as Acer shirasawanum 'Autumn Moon'; Acer palmatum 'Autumn Moon' is listed as a synonym. Its origin is attributed to Japanese maple author and nurseryman J. D. Vertrees. Conifer Kingdom reports that he discovered it as a seedling at Maplewood Nursery in Roseburg, Oregon, while MrMaple separately credits him with both selection and introduction. These accounts support a chance-seedling origin rather than a documented deliberate cross. However, the sources reviewed do not establish its parents or provide a sufficiently verified selection or commercial introduction year. Those details remain undocumented. The cultivar is distinguished by rounded, many-lobed leaves combining yellow-green coloration with orange or pink tones. Patent and cultivar-related registered-trademark status remain unverified, without implying royalty-free propagation or public-domain status.
