Add year-round structure with Pieris japonica 'Interstella®' (Japanese Pieris 'Interstella®'), a broadleaf evergreen shrub prized for its glossy leaves and graceful spring flower clusters. In early spring, drooping trusses of lily-of-the-valley-like blooms brighten the shrub and add welcome seasonal interest, while the foliage stays attractive through the year.
Plant in organically rich, consistently moist, well-drained soil that leans acidic. Choose a site with shelter from drying winds and give the plant full sun to part shade; in warmer areas, afternoon shade helps keep the shrub looking its best. Mulch to conserve moisture and keep roots cool, and water during dry spells, especially while the plant is establishing.
For best flowering, prune only if needed and do it right after bloom, since buds form on previous growth. Use Pieris japonica 'Interstella®' in foundation plantings, shrub borders, or mixed beds with other acid-loving evergreens. Watch for common issues such as lace bugs and leaf spot, and support healthy growth with good air circulation and even moisture.
