Where It Works Best

• Sunlight: Full sun to light part shade (best flowering and most compact growth in full sun; tolerates light afternoon shade)
• Soil: Well-drained loam, sandy loam, or clay loam; thrives in moderately fertile soils; excellent in raised beds, rockeries, and containers with premium potting mix; tolerates Adelaide's alkaline soils; avoid waterlogged sites
• Water Needs:
  • Establishment: Deep soak twice weekly for 8–12 weeks
  • Established: Deep soak every 10–14 days in summer; minimal to no watering in winter once established
• Maintenance: Low maintenance; deadhead spent flower stems after blooming to maintain tidiness and encourage continued flowering; remove any yellowing or damaged foliage; divide congested clumps every 4–6 years in autumn or early spring to maintain vigour and increase stock; feed lightly in early spring with slow-release fertiliser; mulch to retain moisture and suppress weeds; virtually pest and disease-free
• Lifespan: 15–25+ years with periodic division
• Climate Zones: Ideal for Mediterranean and temperate South Australia—Adelaide plains, foothills, Fleurieu Peninsula, coastal and inland gardens
• Soil pH: Neutral to mildly alkaline (pH 6.5–8.0); performs exceptionally well on Adelaide's calcareous soils
