STANDARD / Grevillea 'Grassfire'

Weeping Standard Grevillea ‘Grassfire’

Botanical Name: Grevillea ‘Grassfire’ — Standard (grafted/trained)
Family: Proteaceae
Origin: Australia (garden hybrid)
Plant Type: Evergreen shrub—standard form (single trunk with spreading to weeping canopy)

Overview

Grevillea ‘Grassfire’ is a striking Australian native grevillea, commonly trained as a standard to create a compact feature tree with a rounded to gently weeping canopy. Exceptionally well suited to Adelaide’s Mediterranean climate, it is prized for its vivid red, spider-style flowers and excellent heat and drought tolerance.

Flowering heavily from late winter through spring (with occasional blooms at other times), ‘Grassfire’ provides bold colour, architectural form and outstanding bird appeal. The standard form makes it ideal for courtyards, paths, feature plantings, pots and formal rows where space is limited but impact is desired. Once established, it is tough, waterwise and low maintenance.

Key Features

• Mature Size: 1.5–2.5 m H × 1.5–2.5 m W (overall height depends on graft/stem height; canopy typically 0.8–1.2 m wide)
• Growth Rate: 30-60 cm per year under good conditions
• Foliage: Fine, narrow evergreen leaves; mid- to deep-green with bronze to copper tints on new growth
• Flowers: Bright crimson-red spider-style blooms, nectar-rich; heavy late winter–spring flowering with occasional repeat blooms
• Fragrance: Not fragrant
• Seasonal Interest: Evergreen form year-round with intense winter–spring flowering and coloured new growth
• Wildlife Value: Excellent nectar source for honeyeaters, native birds, bees and other pollinators
• Tolerance: Drought tolerant once established; very heat tolerant; wind tolerant; second-line coastal tolerant; light–moderate frost hardy (young plants benefit from protection in exposed frost-prone areas)
• Planting Density: Feature or avenue planting: space 1.5–2.5 m apart to allow full canopy development
  
• Pet Friendly: Generally considered non-toxic; sap may irritate sensitive skin—wear gloves when pruning

Where It Works Best

• Sunlight: Full sun for strongest flowering and dense canopy; tolerates light part shade
• Soil: Well-drained sandy, loamy or improved clay soils; avoid waterlogging; use low-phosphorus native fertiliser only
• Water Needs: Establishment: 2 deep soaks/week for 8–12 weeks. Established: deep soak every 10–14 days in summer (weekly in heatwaves); monthly in winter if dry
• Maintenance: Low — light tip-pruning after flowering to maintain a neat canopy; remove internal or crossing branches; mulch annually
• Lifespan: 10–20+ years in well-drained sites
• Climate Zones: Ideal for Mediterranean and temperate South Australia — Adelaide Plains, Fleurieu Peninsula, sheltered coastal suburbs
• Soil pH: Slightly acidic to neutral; tolerates mildly alkaline soils if free draining

Landscape & Design Ideas

• Feature standard for courtyards, entrances and focal points
• Formal or semi-formal rows along paths and driveways
• Large pots for patios and alfresco spaces
• Bird-friendly native gardens with lomandra, westringia and callistemon
• Architectural accent in modern and Mediterranean-style landscapes
