Japanese Pieris
Pieris japonica
An elegant broadleaf evergreen that produces cascading clusters of bell-shaped flowers in early spring, often appearing before most other shrubs break dormancy. The glossy evergreen foliage provides year-round interest, and many varieties offer stunning bronze or red new growth that rivals any flower display. This sophisticated shrub brings four-season beauty and a refined presence to shade gardens.
