Scaevola humilis 'Pink Fusion'

Pink Fan Flower

Botanical Name: Scaevola humilis ‘Pink Fusion’
Family: Goodeniaceae
Origin: Australia (cultivar selection)
Plant Type: Evergreen perennial groundcover

Overview

Scaevola humilis ‘Pink Fusion’ is a compact, low-growing Australian native groundcover producing masses of soft to vibrant pink fan-shaped flowers from spring through autumn. Naturally suited to Adelaide’s coastal, dry and Mediterranean climate, it thrives in heat, sandy soils, and windy conditions while maintaining a neat, spreading form. Its semi-succulent green foliage remains attractive year-round, sometimes taking on bronze or red-toned tints in cold weather or very dry periods. Exceptionally resilient and long-flowering, it is ideal for borders, rockeries, native gardens, and container use.

Key Features

• Mature Size: 0.15–0.25 m H × 0.5–0.8 m W (low, spreading habit)
• Growth Rate: 20–40 cm spread per year under good conditions
• Foliage: Fine to mid-textured bright green leaves; evergreen; occasional bronze or reddish tones in winter or dry periods
• Flowers: Abundant pink fan-shaped blooms from spring to autumn; peak flush September–April
  
• Fragrance: Flowers are not considered fragrant; foliage has no noticeable scent
• Seasonal Interest: Very long flowering season with evergreen structure and subtle cool-season foliage tints
• Wildlife Value: Popular nectar source for bees, butterflies and small native pollinators
• Tolerance: Highly drought-tolerant, heat-tolerant and wind-tolerant once established; excellent coastal tolerance (front-line); light frost tolerant with protection from hard frost
• Planting Density: 3–5 plants per m² for a dense carpet
• Pet Friendly: Non-toxic to cats and dogs, though eating large quantities may cause mild stomach upset

Where It Works Best

• Sunlight: Full sun for best flowering; tolerates light or dappled shade with reduced bloom
• Soil: Prefers free-draining sandy or loamy soils; thrives in slightly alkaline or saline coastal soils common across SA
• 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: Light trim after flowering flushes to encourage compact new growth; avoid heavy feeding; if needed, apply low-phosphorus native fertiliser in early spring
• Lifespan: 5–10 years in suitable free-draining conditions
• Climate Zones: Ideal for Mediterranean and coastal South Australia — Adelaide plains, Fleurieu, Yorke and Eyre Peninsulas
• Soil pH: Neutral to alkaline; tolerates slightly acidic if drainage is good

Landscape & Design Ideas

• Coastal gardens needing tough, salt-tolerant colour
• Rockeries, embankments and retaining walls where trailing stems can spill attractively
• Alfresco pots, troughs and hanging baskets for cascading pink flowers
• Low, colourful carpet along sunny paths or mixed native borders
• Waterwise native gardens with Eremophila, Lomandra, Westringia, Dianella, and Chrysocephalum
