White Correa / Native Fuschia / White Correra
Botanical Name: Correa alba
Family: Rutaceae
Origin: Australia (coastal regions of southern Australia, including SA)
Plant Type: Evergreen shrub
Overview
A tough, reliable Australian native shrub, Correa alba is ideal for Adelaide and South Australian gardens, especially coastal and low-rainfall sites. It forms a rounded, compact mound of silvery-green foliage and produces masses of white, star-shaped flowers from autumn through winter, brightening the garden during the cooler months. Its salt, wind, and drought tolerance make it a go-to choice for coastal plantings, low hedges, and native borders. Attractive to birds, hardy, and low-maintenance, it thrives where many plants struggle.
Key Features
- Mature Size: 0.8–1.2 m H × 1–2 m W (naturally compact and rounded)
- Growth Rate: 20-40 cm per year under good conditions
- Foliage: Dense, rounded grey-green to silvery leaves; softly textured; responds well to light clipping
-
Flowers: Small white star-shaped blooms from autumn to winter, occasionally into early spring; lightly aromatic foliage when crushed
- Seasonal Interest: Cool-season flowering and silvery evergreen foliage for year-round structure
- Wildlife Value: Nectar-rich flowers attract honeyeaters and native bees through winter when few plants are in bloom; dense growth offers shelter for small birds
- Tolerance: Excellent drought, wind, and salt tolerance – ideal for front-line coastal sites; Frost tolerant to light–moderate levels; Adapts to poor, sandy, or gravelly soils typical of SA’s coastal regions; Handles reflected heat and exposed sites once established
- Planting Density: Low hedge: 1 per metre for a compact line; Mass planting: 1–1.2 m apart for broader coverage; Feature plant: 1.5–2 m spacing
- Pet Friendly: Non-toxic to cats and dogs; safe for family and pet-friendly gardens
Where It Works Best
- Sunlight: Full sun to part shade (flowers best in full sun)
- Soil: Prefers well-drained sandy or loamy soil; tolerates poor, coastal sands and mildly alkaline soils
- Water Needs: Establishment: 2 deep soaks/week for 8–12 weeks. Established: deep soak every 2–3 weeks in summer (weekly in heatwaves); minimal in winter
- Maintenance: Low-maintenance. Tip prune after flowering to encourage dense regrowth and prolong shape. Mulch annually in spring to retain moisture. Apply a light, low-phosphorus native fertiliser in early spring if needed. Avoid heavy pruning into old wood.
- Lifespan: 15–25+ years in coastal or well-drained sites
- Climate Zones: Thrives in Mediterranean and temperate South Australia, including Adelaide plains, Fleurieu Peninsula, Yorke and Eyre Peninsulas, Barossa foothills, and coastal suburbs
- Soil pH: Adaptable; grows in slightly acidic to moderately alkaline soils if drainage is sharp
Landscape & Design Ideas
- Low informal hedge or clipped native border
- Mass planting for cohesive coastal design or erosion control
- Feature shrub near driveways, paths, or alfresco areas
- Coastal and waterwise gardens – excellent textural and colour contrast
- Pairs beautifully with Westringia, Lomandra, Leucophyta, and Grevillea
