Pieris japonica (pi-ER-is ja-PON-i-ca)

Family: Ericaceae Non-native Shrub (3-15 ft)

Japanese pieris is a woody, broadleaf evergreen shrub in the heath family (Ericaceae). It is native to southeast China, central to southern Japan, and Taiwan where it grows in mountain thickets. The species epithet is Latin for "Japanese." This shrub requires a site with moist, well-drained, acidic soil enriched with organic matter. It grows in full sun to partial shade, preferring some shade when planted in southern gardens. Also, protect it from winter winds. Propagate by stem cutting. Japanese pieris has an upright, rounded, and dense habit and slowly matures to a height of 8 to 10 feet and a width of 6 to 8 feet, though there are dwarf cultivars. It is noted for its emerging coppery red leaves, fragrant white urn-shaped flowers that bloom in the spring, and multi-season interest. The shrub does tolerate pruning, but keep in mind that next season's blossoms will appear on old growth. Use Japanese pieris in the landscape as a specimen or planted in mass to grace landscape borders, home foundations, or Asian gardens. Consider planting native alternatives found in the left column. Quick ID Hints: Reproductive structures (flowers or old fruits) are visible year-round White/pink urn-shaped flowers in pendulous chains New growth is coppery red, and stems are yellow-green Evergreen shrub with sympodial growth, rosette-like leaves Insects, Diseases, and Other Plant Problems: Leaf spot, dieback, and phytophthora blight. Root rot can occur. Nematodes and lace bugs are major problems.
