A Green Upright Japanese Maple
Acer palmatum dissectum ‘Seiryu’ is a unique upright Japanese maple prized for its finely cut green foliage and brilliant red autumn colour. Unlike most dissectum varieties, it grows vertically, making it ideal for small gardens, courtyards, and feature planting
We were first attracted to the fine, lacy green foliage, a soft mid-green that adds texture and contrast to the garden. In autumn, the tree really stands out as the foliage turns brilliant red, gradually deepening to warm gold tones before falling.
Landscaping Uses
Grown primarily for its attractive foliage, Acer ‘Seiryu’ makes an excellent feature tree. It also works well as a small shade tree in compact spaces.
Its upright habit makes it ideal for smaller gardens and courtyards where many other dissectum maples would spread too wide.
It is also well suited to planting near walls or fences, where the fine foliage provides strong visual contrast.
This variety is also suitable for growing in large containers, making it a good choice for patios and outdoor living areas.
Acer palmatum dissectum ‘Seiryu’ – Basic Care
Acer palmatum dissectum ‘Seiryu’ is an easy care Japanese maple that performs best in a protected position. Shelter from hot afternoon sun and drying winds will help prevent leaf scorch and maintain good foliage colour.
Plant in a humus-rich, well-drained soil for best results. Applying a slow-release fertiliser in spring will support healthy growth and overall plant health.
Mulching around the base of the tree will help retain moisture and regulate soil temperature.
Watering
Regular watering is important during the first few summers while the tree is establishing. Once established, Acer ‘Seiryu’ is reasonably tolerant of dry conditions, especially when grown in well-mulched soil and protected from harsh conditions.
Propagation
This cultivar is usually propagated by grafting onto a strong rootstock to ensure vigour and reliability. Hardwood cuttings can be attempted, although the resulting root system may not be as strong as grafted plants.
