About Acer palmatum dissectum 'Seiryu' Upright Laceleaf Japanese Maple
About Acer palmatum dissectum 'Seiryu' Upright Laceleaf Japanese Maple
Acer palmatum dissectum 'Seiryu' is the only commonly grown upright laceleaf Japanese Maple. Where most dissectum cultivars cascade downward, Seiryu grows upward on a sculptural vase-shaped frame, carrying finely dissected green foliage that turns vivid orange, red and gold in autumn.
Seiryu grows slowly to 3-4 metres tall and 2-3 metres wide. The upright compact form makes it unusually versatile for a laceleaf maple, suiting courtyards, layered garden borders, Japanese-style designs, and large feature pots where height is wanted without sacrificing the delicacy of dissected foliage.
Seiryu 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 delicate dissected foliage from scorching, in well-drained soil with consistent moisture during dry spells.
Seiryu or Inaba Shidare? Both are dissectum (laceleaf) Japanese Maples with finely cut foliage. Seiryu is the only commonly grown upright laceleaf, with green spring foliage turning vivid red and gold in autumn. Inaba Shidare has a cascading weeping habit with burgundy-red foliage that intensifies in autumn. Choose Seiryu for upright height, or Inaba Shidare for cascading colour.
