Pratia pedunculata

Blue Star Creeper / Pratia

Botanical Name: Pratia pedunculata
Family: Campanulaceae
Origin: Australia & New Zealand
Plant Type: Evergreen groundcover perennial

Overview

A tough, low-growing native groundcover ideal for Adelaide’s Mediterranean climate, Pratia pedunculata forms a dense, spreading mat of fine green foliage dotted with masses of small, star-shaped white to pale blue flowers from spring through summer. Naturally adapted to dry conditions and poor soils, it’s a reliable choice for filling gaps between pavers, edging paths, softening garden borders, and stabilising slopes.

Hardy, fast to establish and highly adaptable, Pratia pedunculata copes well with heat, light foot traffic, coastal exposure and periods of dryness once established. Its neat habit suppresses weeds and provides year-round greenery, making it a practical and attractive alternative to lawn in low-use areas.

Key Features

Where It Works Best

• Sunlight: Full sun to light part shade; flowers best with sun, foliage remains denser with some shade
• Soil: Free-draining sandy or loamy soils; tolerates poor, rocky and slightly alkaline soils common across Adelaide
• Water Needs: Establishment: 2 deep soaks/week for 6–8 weeks. Established: occasional deep watering during extended dry periods
• Maintenance: Very low — trim edges if spreading beyond boundaries; no regular feeding required
• Lifespan: 5–10+ years, easily renewed by natural spread
• Climate Zones: Well suited to Mediterranean and temperate South Australia — Adelaide Plains, foothills, Fleurieu Peninsula, Yorke Peninsula and coastal suburbs
• Soil pH: Neutral to alkaline; tolerates slightly acidic soils if well drained
