Originating from Japan.
A distinctive acer with long slender-looking leaves. The deeply divided leaflets are separate almost to the leaf stalk and are in fact broad in the middle, tapering sharply toward the tip and base, giving them an oval shape. Their margins are finely serrated and have a unique wine-red colour becoming fiery scarlet in the autumn, and form a wide spreading canopy over a tracery of elegant branches. Should be grown in dappled shade to avoid leaf scorch, although it is hardy and easy to grow in moisture-retentive soil, or in pots.
Height and spread after 15 – 20 years if not pruned 6m x 5m.
