Grevillea rosmarinifolia 'Rosy's Baby'

Rosy's Baby Rosemary Grevillea

Botanical Name: Grevillea rosmarinifolia 'Rosy's Baby'
Family: Proteaceae
Origin: Australia (south-eastern); dwarf cultivar
Plant Type: Evergreen compact shrub

Overview

'Rosy's Baby' is a dwarf, dense form of the rosemary grevillea with fine, needle-like green foliage and pink-and-red spider flowers carried through the cooler months. Its naturally compact, low-rounded habit suits small gardens, low informal hedges and borders, while its nectar-rich flowers draw honeyeaters and small birds. Tough, frost-hardy and water-wise once established — an easy, bird-friendly native for SA.

Key Features

• Mature Size: 0.6–1 m H x 0.6–0.8 m W
• Growth Rate: Moderate; 15–30 cm per year; dense, low-spreading and rounded with fine texture
• Foliage: Fine, needle-like deep-green leaves (rosemary-like); soft, dense year-round cover
• Flowers: Pink-and-red spider flowers; main display winter–spring with scattered flowering at other times; non-fragrant
• Seasonal Interest: Peak winter–spring flowering; fine evergreen foliage year-round
• Wildlife Value: Excellent bird attractant — honeyeaters forage the flowers; provides low shelter for small birds
• Tolerance: Drought-tolerant once established; frost hardy; heat-tolerant; wind-tolerant; coastal-tolerant (second-line); clay-tolerant if well-drained
• Planting Density: Low informal hedge: 80 cm–1 m apart; mass planting: 80 cm apart; feature: 1–1.5 m clearance
• Pet Friendly: Generally non-toxic, but grevillea foliage and flowers can cause contact dermatitis in sensitive pets and people — discourage chewing

Where It Works Best

• Sunlight: Full sun for best flowering and density; tolerates light shade
• Soil: Well-drained loam, sandy loam or clay loam; avoid phosphorus-rich fertilisers and waterlogging
• Water Needs: Establishment: 2 deep soaks per week for 8–12 weeks. Established: deep soak every 2–3 weeks in summer; seldom in winter unless prolonged dry.
• Maintenance: Light tip prune after main flowering to keep compact; avoid cutting into old bare wood; low-phosphorus native fertiliser only; mulch in spring
• Lifespan: 12–20 years
• Climate Zones: Suited to temperate and Mediterranean SA — Adelaide metro, Hills and second-line coastal
• Soil pH: Slightly acidic to neutral (pH 5.5–7.0)

Landscape & Design Ideas

• Low informal hedge or border in native and water-wise gardens
• Bird-attracting mass planting beneath taller shrubs
• Compact filler for rockeries, slopes and dry banks

Why You Will Love It
