Where It Works Best

• Sunlight: Full sun (essential for best flowering, most compact growth, and strongest fragrance; tolerates very light shade)
• Soil: Exceptionally well-drained sandy loam, gravelly soil, or rocky soil; thrives in poor, lean soils; excellent in raised beds, rockeries, and containers; will not tolerate heavy clay or waterlogged conditions
• Water Needs:
  • Establishment: Deep soak twice weekly for 6–8 weeks
  • Established: Deep soak every 14–21 days in summer (or less—extremely drought-tolerant); minimal to no watering in winter
• Maintenance: Low maintenance; deadhead spent flower spikes to prolong blooming and maintain tidiness; cut back by one-third to one-half in late winter to encourage fresh, bushy growth; avoid fertilisers (thrives in lean soils); excellent for cut flowers and dried arrangements; virtually pest and disease-free
• Lifespan: 5–10+ years (may become woody with age; light pruning extends lifespan; easy to replace)
• Climate Zones: Ideal for Mediterranean and temperate South Australia—Adelaide plains, foothills, Fleurieu Peninsula, sheltered coastal and inland gardens; thrives in hot, dry, exposed sites
• Soil pH: Neutral to mildly alkaline (pH 6.5–8.0); performs exceptionally well on Adelaide's calcareous soils
