Pieris japonica 'Mountain Fire' is an evergreen shrub grown for its striking seasonal foliage and spring flowers. New growth emerges in vivid red tones, creating a strong contrast before gradually turning deep green as the leaves mature. In spring, the plant produces hanging clusters of small white flowers beneath the foliage, adding an additional layer of interest. Growth is upright and well-branched, forming a tidy shrub without the need for frequent pruning. As an evergreen, it provides year-round structure and colour and performs best in acidic soil where both foliage and flowering develop fully.
