Where It Works Best

• Sunlight: Full sun to light part shade (best flowering in full sun)

• Water Needs: Establishment: 2 deep soaks/week for 8–12 weeks. Established: deep soak every 10–14 days in summer; monthly in winter if dry
• Maintenance: Mulch in spring; tip-prune after flowering to keep compact (avoid cutting into old bare wood)
• Lifespan: 10–20+ years
• Climate Zones: Suited to temperate and Mediterranean SA gardens, including coastal areas
• Soil pH: Slightly acidic to mildly alkaline —tolerates limestone with drainage

Landscape & Design Ideas

• Privacy screening and boundary hedges with a refined finish
• Mass plant for cohesive, low-maintenance colour and bird appeal
• Feature near entries, paths and outdoor living spaces; suitable for large pots with free-draining native mix
