Overview

A stunning Australian native lilly pilly clipped into a formal sphere, perfectly suited to Adelaide's Mediterranean climate. Acmena smithii 'Allyn Magic' features a neat, dense canopy of glossy deep green foliage with distinctive bronze-copper new growth flushes, creating year-round visual interest and elegant formality. Compact, naturally dense and non-invasive, it responds beautifully to clipping while maintaining vibrant colour. Exceptionally versatile, drought-tolerant and low-maintenance once established, this native sphere brings Australian elegance, seasonal colour and reliable performance to formal gardens, entrances, courtyards and containers across South Australian landscapes.

Key Features

• Mature Size: 0.8–1.2 m H (sphere diameter) × 0.8–1.2 m W; can be maintained smaller or larger with regular clipping
• Growth Rate: 20–40 cm per year under good conditions (managed through regular clipping)
• Foliage: Small, glossy deep green oval leaves; spectacular bronze-copper to burgundy new growth flushes throughout the growing season; dense, fine-textured branching; evergreen year-round with stunning seasonal colour interest
• Flowers: Small creamy-white fluffy flowers in spring (minimal on heavily clipped spheres; not the main ornamental feature)
• Fruit: Small pink to red berries may appear if flowering occurs (minimal on regularly clipped topiary forms)
• Fragrance: Not fragrant
• Seasonal Interest: Evergreen structure year-round with spectacular bronze-copper new growth flushes in spring and summer; maintains vibrant colour through all seasons
• Wildlife Value: Minimal on clipped forms; flowers and fruit (when present) attract birds and bees
• Tolerance: Excellent drought tolerance once established; heat-tolerant; frost-tender when young (protect from hard frosts below -2°C; established specimens tolerate light frosts); wind-tolerant; coastal-tolerant in sheltered positions; requires well-drained soil—will not tolerate waterlogging
• Planting Density: Formal rows/hedging: Space 1.0–1.5 m apart; Specimen/feature: 1 plant per focal point or large container (minimum 50–60 cm diameter pot)
• Pet Friendly: Yes—non-toxic and safe for pets

Where It Works Best

• Sunlight: Full sun to part shade (best bronze new growth colour and most compact form in full sun; tolerates light shade)
• Soil: Well-drained loam, sandy loam, or improved clay loam enriched with organic matter; tolerates Adelaide's alkaline soils; excellent in premium potting mix for containers; avoid waterlogged sites
• Water Needs:
  • Establishment: Deep soak twice weekly for 12–16 weeks
  • Established: Deep soak weekly in summer (more during extreme heatwaves or for container specimens); fortnightly in spring and autumn; minimal watering in winter once established
• Maintenance: Moderate maintenance; tip-clip 2–4 times per year during active growth (spring–autumn) to maintain tight sphere form and encourage dense growth and bronze flushes; feed in early spring and midsummer with slow-release or low-phosphorus native fertiliser; mulch in-ground plants; rotate container specimens quarterly for even sun exposure; generally pest and disease-free (occasional psyllid—minor, easily managed)
• Lifespan: 30–50+ years with proper care and maintenance
• Climate Zones: Ideal for Mediterranean and temperate South Australia—Adelaide plains, foothills, Fleurieu Peninsula, sheltered coastal gardens; performs best in warmer, sheltered microclimates
• Soil pH: Slightly acidic to neutral (pH 5.5–7.0); tolerates mildly alkaline soils (up to pH 7.5) if well-drained
