Pieris
Pieris japonica
shrubPieris is a broadleaf evergreen shrub prized for its ornamental foliage and delicate, fragrant flower clusters that resemble lily-of-the-valley. It features glossy, leathery leaves that often emerge in vibrant red or bronze tones before maturing to deep green, and produces cascading panicles of small, bell-shaped white or pink flowers in early spring. This shade-loving shrub adds year-round structure and seasonal interest to woodland gardens and shaded borders.
