(Pieris japonica)

Contact: Diane Relf, Extension Specialist, Environmental Horticulture

August 1996

Summary:

Foliage: Evergreen broadleaf
Height: 9 to 12 feet
Spread: 6 to 8 feet
Shape: Bushy

Hanging clusters of pink or white flowers bloom in early spring. New foliage is bronze in spring, but turns glossy green for the rest of the year.

Plant Needs:

Zone: 5 to 8
Light: Partial shade to full sun
Moisture: Moist
Soil Type: Sandy, loam, or clay
pH Range: 3.7 to 5.5

Functions:

Suggested uses for this plant include border, foundation, massing, and specimen plant.

Planting Notes:

Transplant using plants that have balled and burlapped roots or those that are container grown.
Plant in well-drained, acid soil which has been supplemented with peat moss or organic matter.
Place in a location that is protected from winter sun and harsh winter winds.

Care:

Tends to get leggy and needs pruning to keep it bushy.
Clip off old flower heads after flowers fade in spring. This allows new flower buds to develop for the following year.

Problems:

Lacebug sucks leaf juices, causing foliage to turn yellow to brown.
Red spider mites, leaf spots, and dieback are other problems.
Root rot may occur in poorly-drained soil.

Alternatives:

Consult local sources, including historic or public gardens and arboreta, regarding cultivars and related species that grow well in your area.

Cultivars of PIERIS JAPONICA:
`Dorothy Wycoff' is a compact form with pink flowers.
`White Cascade' has long strings of white flowers which last for several weeks.

Comments:

An excellent specimen, border, or foundation shrub. It also does well in natural settings.
A graceful, clean-looking plant which, with care, can provide year round landscape interest.
If using this plant in a foundation planting, be careful not to locate under a window where its ultimate height will require severe pruning.
