===== About =====

*Pieris japonica* is one of the finest spring-flowering shrubs for a Pacific Northwest garden. The long, drooping panicles of small bell-shaped flowers (resembling lily-of-the-valley) appear in late winter to early spring, often before most other things are blooming. The foliage is an added attraction: new growth emerges in brilliant shades of red, bronze, or copper before maturing to glossy dark green.

===== Key Characteristics =====

  * **Type:** Evergreen shrub, family Ericaceae
  * **Flowers:** Small urn-shaped flowers in drooping panicles; white to deep pink depending on cultivar; February–April
  * **Foliage:** Glossy dark green; new growth colourful (red/bronze/cream depending on variety)
  * **Size:** Typically 2–4 m tall and wide; slow-growing
  * **Form:** Rounded, layered habit
  * **Toxic:** All parts are toxic if ingested — keep away from livestock and pets

===== Care Notes =====

^ Aspect          ^ Details ^
| **Hardiness**   | Hardy to −15°C (Zone 6); performs beautifully in the Pacific Northwest |
| **Soil**        | Acidic (pH 4.5–6.0), humus-rich, moisture-retentive but well-drained — ideal under conifers |
| **Sun**         | Dappled shade to part shade; protect from harsh afternoon sun and drying winds |
| **Watering**    | Keep consistently moist, especially in summer; mulch well to retain soil moisture |
| **Pruning**     | Minimal — deadhead spent flower clusters after blooming; light shaping if needed |
| **Fertilising** | Feed with an ericaceous (acid) fertiliser in spring |
| **Pests**       | Lace bugs can cause bronzing of foliage in stressed plants; vine weevil occasionally |

===== Notes =====

  * Flower buds set in autumn and are visible through winter — avoid late frosts which can damage buds
  * Excellent companion for Rhododendrons, Azaleas, and other acid-loving plants
  * The cultivar in this garden appears to have mid-pink flowers
  * Mulching with bark or pine needles maintains soil acidity and moisture
