Eucalyptus Torquata

Coral Gum / Coolgardie Gum

Botanical Name: Eucalyptus torquata (Coral Gum)
Family: Myrtaceae
Origin: Australia
Plant Type: Evergreen tree

Overview

A compact, show-stopping gum for South Australian gardens. Coral Gum carries blue- to grey-green foliage and spectacular clusters of coral-pink to orange-red blossoms that smother the canopy in the cooler months—bringing bees and honeyeaters when little else is flowering. Perfect as a feature or small street tree for low-water, coastal and Mediterranean designs.

Key Features

• Mature Size: 4–8 m H × 3–6 m W (small, spreading tree)
• Growth Rate: 40-80 cm per year under good conditions
• Foliage: Evergreen blue/grey-green lance leaves; smooth, patchy bark; tidy, rounded habit
• Flowers: Showy, nectar-rich clusters mainly late winter–spring; decorative gumnuts follow
  
• Seasonal Interest: Reliable year-round structure and bark interest; peak flowering late winter–spring
• Wildlife Value: High—nectar for bees and honeyeaters; canopy offers shelter for small birds
• Tolerance: Drought-tolerant (once established), heat-tolerant, wind-tolerant, second-line coastal-tolerant; light frost (protect young growth); clay-tolerant with improved drainage
• Planting Density: Avenue/specimen: 1 tree per 16–36 m² (4–6 m apart), depending on mature canopy
• Pet Friendly: No — toxic to pets (eucalypt oils); prevent chewing of leaves/pods

Where It Works Best

• Sunlight: Full sun (needs open sky for best flowering and form)
• Soil: Well-drained loam or sandy loam; thrives on alkaline/limestone soils; avoid waterlogging
• 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: Mulch in spring; formative prune while young (don’t top); remove spent gumnuts if desired; minimal feeding
• Lifespan: 25-50+ years
• Climate Zones: Suited to temperate and Mediterranean SA gardens, including coastal areas
• Soil pH: Acid, Neutral, Alkaline — adaptable; excels on slightly alkaline/calcareous sites with drainage

Landscape & Design Ideas

• Feature/specimen near entries and terraces for dramatic coral blooms
• Avenue on driveways or rural blocks (allow canopy space)
• Low-water native schemes with lomandra, westringia and eremophila
