- Description
-
Japanese Pieris is a slow-growing evergreen shrub to a small tree in the Ericaceae (heath) family. 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 inflorescences that bloom in the spring. Blooms are present for 2-3 weeks. Dried inflorescence persists into winter unless removed. Sympodial growth features crowded, rosette-like leaves on greenish-yellow twigs. New growth is bronze-red or purplish.
This plant is native to eastern China, Taiwan, and Japan where it grows in mountain thickets typically reaching a height of 9 to 13 feet.
This plant prefers full sun to partial shade. Some shade is required in southern gardens. It prefers moist, well-drained, acidic soil enriched with organic matter. It is intolerant to wet soils and needs protection from winter winds.
Use in the landscape as a specimen, in massing, foundations, and borders. Due to the toxicity of the leaves and nectar of this plant, if ingested, the Japanese Peris should be used with caution around young children and pets.
