Distinctive Features

This evergreen azalea is known for abundant white flowers in spring, often highlighted by a soft yellow-green blotch in the throat. The habit is dense and mounded, creating a full shrub that works well in foundation beds and low hedges. Dark green foliage provides a solid backdrop for the blooms and holds well through much of the year in suitable climates. Mature size is typically about 3 to 4 feet tall and about 4 to 5 feet wide, forming a broad, garden-friendly shape.

Growing Conditions

• Sun: Part shade is ideal, with morning sun and afternoon shade helping protect flowers and foliage.
• Soil: Acidic, humus-rich, well-drained soil, and avoid heavy, wet, or alkaline conditions.
• Water: Moderate, keep evenly moist during establishment, then water during dry periods to reduce stress.
• USDA Zones: 6 to 8.
• Site: Shelter from drying wind and hot reflected heat to help foliage stay cleaner and reduce scorch.

Ideal Uses

• Focal Point: Use one plant as a spring focal point where the white flowers can brighten an entry bed or shaded border.
• Foundation Planting: Plant along foundations for evergreen structure and a crisp spring flower display.
• Low Hedge: Use in a short row for a tidy evergreen hedge that blooms clean white in spring.
• Shrub Borders: Mix with other acid-loving shrubs for layered texture and a calm, classic color scheme.
• Woodland Edge: Tuck into lightly shaded borders where the natural mound form blends easily with perennials.

Low Maintenance Care

• Pruning: Prune lightly right after flowering to shape, since later pruning can reduce next seasons buds.
• Mulching: Mulch to keep roots cool and moisture steady, keeping mulch a few inches away from the base.
• Watering: Water during summer dry spells to prevent stress and support healthier foliage.
• Feeding: Feed in spring with an acid-loving shrub fertilizer if needed, following label directions.
• Soil Health: Improve planting areas with organic matter to support drainage while holding consistent moisture.
