Acer palmatum 'Osakazuki' is widely regarded as one of the finest autumn-colour Japanese Maples ever selected. Bright green summer foliage transitions to a brilliant scarlet-crimson in autumn that is rapid, intense, and often outshines every other Acer palmatum cultivar in the garden.
Osakazuki grows to 5-6 metres tall and 4-5 metres wide with a rounded upright canopy. The moderate size and well-structured habit suit residential gardens, courtyards, Japanese-style landscapes, large pots, and bonsai work, where the autumn display becomes a striking seasonal focal point.
Osakazuki performs best in cool to temperate regions including VIC, NSW Southern Highlands, ACT, Tasmania, and elevated parts of SA and WA. In warmer climates plant in part shade to protect the foliage from scorching, in well-drained soil with consistent moisture during dry spells.
Osakazuki or Atropurpureum? Both are upright Acer palmatum cultivars. Osakazuki has bright green summer foliage that transitions to famously brilliant scarlet in autumn. Atropurpureum holds deep burgundy-purple foliage through the whole growing season. Choose Osakazuki for explosive autumn impact, or Atropurpureum for continuous purple foliage.
