General Culture:

Easily grown in moist, organically rich, well-drained soils in full sun to part shade. Best performance is in sun-dappled part shade. Avoid hot, dry sites. Plant in locations protected from strong winds.

Noteworthy Characteristics:

Japanese maple is a multi-stemmed shrub or single-stemmed small tree that typically grows to 10-25’ tall. Although general plant form for dissected (cutleaf/laceleaf) cultivars is cascading or weeping, ‘Seiryu’ is the exception. It is the only dissected cultivar that has an upright form. Mature plants may grow to as much as 10-15’ tall. Deeply cut and dissected leaves (to 2” long) are smaller than the leaves on most other dissectum cultivars. Leaves emerge light green with reddish tipped edges in spring, mature to medium green in summer and turn gold with orange and red hues in fall. Small reddish-purple flowers in spring are somewhat attractive on close inspection, but are not showy from a distance. Cultivar name means green dragon.

Problems: Click for detailed list of pests and problems.

No serious insect or disease problems. Susceptible to stem canker and leaf spots. Verticillium wilt may also occur. Watch for borers, scale, mites and aphids. Foliage tends to leaf out early in spring and is subject to damage from late spring frosts. Leaves may scorch in full sun.

Uses:

Japanese maples are generally grown for their attractive foliage and shape. Specimen/accent or group around the home or yard or periphery of the border or rock garden. May be grown in tubs/patio containers.
