Acer palmatum dissectum 'Seiryu' (Say-roo)
Japanese Maple

Description:

General: This is the only* upright dissectum cultivar. Vase-shaped to 15 feet in height and broadening as it gets older.
Sei- green. Ryu-dragon.

Leaves: Seven pinnately dissected lobes on short, stiff petioles. The leaves emerge a brilliant green tipped with reddish-pink tones then turns to all green. Beautiful! Also, a flush of bright green is displayed in mid- late summer. Autumn foliage is spectacular! This tree seems to light on fire. Yellow, orange, red, pink... a kaleidoscope of color.

Flowers: Insignificant

Fruit: Samaras, not too showy

Bark: Dark brown-green/yellow with red stems

Culture:

Growing Conditions: Sun to partial shade. Prefers well-drained moist soil.

Maintenance: Very low maintenance, light pruning needed only to shape.

Transplanting: Spring or after the leaves have begun to change in the fall.

Hardiness:
Zone 5 to 8.

Experience at Great Hill:
The cold hardiness of 'Seiryu' is questionable and is being closely observed.

Attributes:
In the right location, this unique and unusual dissectum maple makes a great specimen with outstanding color throughout the growing season. It's a welcomed contrast when planted with the standard cascading type dissectums.

*'Lionheart' could be called upright, however, it is smaller and grows wider than taller with the tips becoming pendulous in time.
