Fullmoon maple is a small deciduous tree from Japan, Korea and the Kuril Islands, grown mainly as an ornamental for its large, lobed leaves that turn bright orange to dark red in autumn. Give it sheltered, partly shaded conditions similar to Japanese maple, and it tolerates cold better than the more delicate cultivars of Acer palmatum.

About
Acer japonicum, fullmoon maple, or downy Japanese-maple (Japanese: はうちは楓, romanized: hauchiwakaede), is a species of maple native to Japan, on Honshū, Hokkaidō, Kyūshū (Nagasaki Prefecture), and also southern Korea.
How to grow it
Acer japonicum is frequently cultivated as an ornamental plant in temperate regions of Europe, North America, and elsewhere, though much less commonly than Acer palmatum. In cultivation, it is often only a shrubby tree with multiple trunks joining at ground-level.
Its preferred growing conditions are similar to those of Acer palmatum, but it is sometimes considered more tolerant of cold, especially compared to the more delicate cultivars of the latter.
