About
Acer shirasawanum, the Shirasawa maple or fullmoon maple (Japanese: オオイタヤメイゲツ, romanized: ooitayameigetsu), is a species of maple native to Japan, on central and southern Honshū (Fukushima Prefecture southwards), Shikoku, and Kyūshū.
How to grow it
It is grown as an ornamental tree in gardens for its foliage and autumn colour, but is seen far less commonly than Acer palmatum (Japanese maple). A number of cultivars have been selected; the lighter-coloured A. shirasawanum cultivar 'Aureum' is very widely grown, much more common in cultivation than the main species, and has gained the Royal Horticultural Society's Award of Garden Merit.
It is propagated by grafting onto more hardy and fast-growing Acer species, in particular A. palmatum and A. japonicum.
