Acer palmatum dissectum ‘Seiryu’ - Acer palmatum dissectum ‘Seiryu’

Acer palmatum dissectum 'Seiryu'

One of the few dissectum maples that grows upright, 'Seiryu' delivers the intricate laceleaf texture of a weeping Japanese maple with genuine vertical presence. A refined specimen for considered landscapes where structure and seasonal drama are both required.

Why Seiryu

Upright dissected form: The only commonly available laceleaf maple with a strongly vertical habit, reaching 4–6 metres at maturity.
Exceptional autumn colour: Foliage transitions through gold, amber, and deep crimson as the season progresses.
Lightweight, textured canopy: Finely cut leaves create movement and filtered light without visual weight.
Year-round presence: Architectural branch structure maintains interest through winter dormancy.
Proven performer: Reliable and long-lived when sited correctly; a low-intervention specimen for professional projects.

Ideal Applications

Prestige residential feature: A commanding focal point in contemporary or Japanese-influenced landscape schemes.
Courtyard and enclosed spaces: Upright habit makes it well-suited to restricted footprints where a weeping form would be impractical.
Large-format container planting: Performs with distinction in substantial pots with adequate drainage, ideal for terraces and rooftop projects.
Layered planting compositions: Introduces fine texture and seasonal contrast against evergreen structure planting.

Specimen & Installation

Spacing (feature/avenue): 4–6m
Planting Season: Autumn to early spring when dormant
Soil & Drainage: Moist, well-drained, slightly acidic soil rich in organic matter; avoid waterlogged or highly alkaline conditions
Establishment Care: Water deeply and regularly during the first two summers to establish a strong root system, particularly in warmer or drier regions of Australia. Apply a generous layer of organic mulch around the base to retain soil moisture and protect shallow roots from heat stress.
