|Acer japonicum is a tree in its native habitat and a large tree-like shrub in cultivation. This bushy, deciduous tree with rounded mid-green leaves turn red in the autumn. Small, red-purple flowers appear in April in long drooping corymbs. Leaves tend to scorch in hot, dry weather.
The cultivar, 'Filiforme' is a small, treelike shrub much like 'Aconitifolium' but with smaller, fewer lobed leaves. It is very free flowing.
