Pieris japonica 'Avalanche' (often called Lily-of-the-Valley Shrub 'Avalanche') brings year-round structure with broadleaf evergreen foliage and a big spring show of drooping, lily-of-the-valley-like white flower clusters.

Plant it where you can enjoy the early-season bloom and the persistent flower buds that form on the previous season's growth. A sheltered spot out of harsh winter sun and drying winds can help reduce leaf scorch and protect buds in colder climates.

You will get the best performance in moist, well-drained, acidic soil rich in organic matter. Work in composted bark or leaf mold at planting time, keep the root zone evenly moist (not soggy), and mulch to maintain cool soil and steady moisture. Avoid alkaline soils and poorly drained sites, which can stress the plant over time.

In the landscape, use this shrub for foundation plantings, woodland-style beds, or mixed borders alongside other acid-loving evergreens. It tolerates full sun in cooler areas but is especially at home with afternoon shade or light, filtered shade. Mature size for this selection is typically around 48-60 inches tall with a similar spread.

As with many pieris, all parts are considered toxic if ingested, so place it thoughtfully around pets and children. Prune only as needed, and do it right after flowering to avoid removing next year's buds.
