Japanese Pieris is a slow-growing evergreen shrub to small tree that grows 9-13 feet tall in the heath family, Ericaceae. It is native to eastern China, Taiwan, and Japan where it grows in mountain thickets. It is an upright to spreading ornamental shrub, noted for its emerging bronzed foliage, showy floral buds that mature in late summer and are attractive in fall and winter, and showy white (or pink) inflorescences that bloom in late winter to early spring and blooms are effective for 2-3 weeks. Dried inflorescence persists into winter unless removed. Sympodial growth with crowded, rosette-like leaves on greenish-yellow twigs. New growth is bronze-red or purplish. It is used as a specimen, massing, foundations, and borders. Some shade is required in southern gardens.
This plant prefers full sun to partial shade. Prefers moist, well-drained, acidic soil enriched with organic matter. It is is intolerant of wet soils and need protection from winter winds.
Problems: Leaf spot, dieback, nematodes, and lace bug are major problems.
