Pieris japonica, is known by many names, including Japanese andromeda, lily-of-the-valley shrub and Japanese pieris; it is a species of upright to spreading broadleaf evergreen flowering shrub in the heath family Ericaceae. Native to eastern China, Taiwan, and Japan, it grows in mountain thickets. This variety is a medium-sized evergreen shrub or ornamental tree, and is widely cultivated in gardenscapes for its year round beauty and interesting flowers.
Pieris requires acid soil which is moist but well-drained, and a sheltered, full sun to partially shaded spot - they will grow in deep shade, but generally do not flower as well and the new foliage growth is usually not as brilliant. Feed with an acid fertilizer after bloom.
Japanese Pieris has oblong leaves that begin the season with bright red foliage transitioning to a reddish-bronze color and transforms into glossy, leathery green foliage ( changes color throughout the seasons), and in late summer or fall, long, dangling clusters of flower buds appear; these buds open into dramatic, creamy-white blossoms in spring, and are present for 2 to 3 week
