Grevillea 'Bonnie Prince Charlie'

Bonnie Prince Charlie Grevillea

Botanical Name: Grevillea ‘Bonnie Prince Charlie’
Family: Proteaceae
Origin: Australia (hybrid selection)
Plant Type: Evergreen shrub

Overview

Grevillea ‘Bonnie Prince Charlie’ is a striking Australian native shrub ideally suited to Adelaide’s Mediterranean climate, valued for its finely divided foliage and vivid red to deep pink spider-style flowers that appear over a long season from winter through spring, often extending into summer. Naturally tolerant of heat, dry conditions and poor soils, it performs reliably across South Australia in full sun and free-draining ground. Its airy, spreading habit and soft grey-green foliage create year-round texture, while the nectar-rich flowers provide an important food source for birds and pollinators. Tough, waterwise and visually dramatic, it is an excellent choice for native gardens, low-maintenance borders and informal screening.

Key Features

• Mature Size: 1–2 m H × 1.5–3 m W (spreading, open shrub)
• Growth Rate: 20–40 cm per year under good conditions
• Foliage: Fine, deeply divided grey-green foliage with silvery undertones; new growth may show soft bronze or pale green tints
• Flowers: Showy red to deep pink spider-style flowers with pale highlights, flowering mainly winter–spring with repeat blooms at other times
  
• Fragrance: Not fragrant (flowers); foliage may have a faint resinous native scent when handled
• Seasonal Interest: Evergreen foliage provides year-round structure; peak flowering in winter and spring brings strong colour when many gardens are quiet
• Wildlife Value: Highly attractive to honeyeaters, native bees and other pollinators; dense branching offers shelter for small birds
• Tolerance: Drought tolerant once established; excellent heat tolerance; wind tolerant; coastal tolerant (second-line, sometimes first-line with good drainage); light frost hardy; dislikes waterlogged or heavily enriched soils
• Planting Density: Feature or informal shrub: space 1.5–2.5 m apart; screening or mass planting: 1–2 m apart depending on desired density
• Pet Friendly: Generally safe, though grevillea foliage can cause skin irritation for sensitive people or animals—discourage handling or chewing

Where It Works Best

• Sunlight: Full sun for best flowering and compact habit; tolerates light part shade with reduced bloom
• Soil: Free-draining sandy, loamy or gravelly soils; tolerates limestone and mildly alkaline soils common in Adelaide; avoid heavy clay unless well improved
• Water Needs: Establishment: 2 deep soaks per week for 8–12 weeks. Established: deep soak every 10–14 days in summer; minimal watering in winter
• Maintenance: Low; light tip-pruning after flowering to maintain shape and encourage dense growth; avoid heavy pruning into old wood; use low-phosphorus native fertiliser only if required
• Lifespan: 10–25+ years in well-drained conditions
• Climate Zones: Ideal for Mediterranean and temperate South Australia — Adelaide Plains, Fleurieu Peninsula, Yorke Peninsula, coastal suburbs
• Soil pH: Slightly acidic to mildly alkaline; performs well on limestone with good drainage

Landscape & Design Ideas

• Feature shrub in native, coastal or Mediterranean-style gardens
• Informal screening or habitat planting for birds
• Mixed native borders with Westringia, Lomandra, Callistemon and Eremophila
• Low-water landscapes and gravel gardens
• Coastal and wind-exposed sites where tougher plants are required
