Acer palmatum 'Seiryu'Japanese maple
It brings the delicacy of the deeply cut leaves of the Dissectum maples to a tree of upright growth. This unusual combination creates a vertical, light, transparent crown, very different from the low, weeping forms that characterise most cultivars in this group.
- One of the rare Japanese maples in the Dissectum Group with upright growth
- Finely cut green foliage that gives the crown great lightness and transparency
- Multicoloured autumn colour, combining yellow, orange and crimson red
About this cultivar
‘Seiryu’ develops an architecture that is narrow and broadly columnar at first, becoming more open and irregular with age. It generally reaches 3 to 4.5 metres in height and around 2.5 to 3.5 metres in spread, forming a small upright tree rather than the usual domed, weeping crown of the Dissectum maples.Read moreShow less
‘Seiryu’ develops an architecture that is narrow and broadly columnar at first, becoming more open and irregular with age. It generally reaches 3 to 4.5 metres in height and around 2.5 to 3.5 metres in spread, forming a small upright tree rather than the usual domed, weeping crown of the Dissectum maples.
The leaves are deeply divided to the base into narrow, doubly serrate lobes. Despite their lacy texture, they are carried along ascending branches, creating successive planes of foliage through which light and views pass. This pairing of cut leaf and upright habit is what makes the cultivar truly singular.
The foliage opens lime green, often with reddish tips, and matures to light green during the summer. In autumn, the crown brings together tones of golden yellow, orange and crimson red at the same time, producing a colour change that is varied rather than uniform.
It prefers a sheltered position, with gentle sun or partial shade, and fertile, moist, well-drained soil. Protection from intense afternoon sun and dry winds helps to preserve the integrity of the finely cut foliage, particularly in the warmer regions of Portugal.
It is suited to small gardens, courtyards, entrances and compositions that call for a vertical presence without losing transparency. A mature specimen from Diaplant immediately brings an upright, branched crown, high enough to read as a small tree, offering the texture of a Dissectum without taking up the horizontal space of the weeping forms.
