Eucalyptus Leucoxylon Rosea

Pink-Flowering Yellow Gum / Red Flowering Yellow Gum / Pink Flowering Gum

Botanical Name: Eucalyptus leucoxylon rosea (Pink-flowering SA Blue Gum)
Family: Myrtaceae
Origin: Australia (SE Australia incl. SA & Vic)
Plant Type: Evergreen tree

Overview

A compact-to-medium gum ideal for South Australian gardens. The pink-flowering form of SA Blue Gum carries a neat, rounded canopy of blue- to grey-green foliage and puts on generous cool-season displays of nectar-rich pink to red blooms that feed birds and bees. Excellent as a feature or street/driveway tree in low-water, coastal and Mediterranean settings.

Key Features

• Mature Size: 6–12 m H × 4–8 m W (smaller with formative pruning)
• Growth Rate: 40-80 cm per year under good conditions
• Foliage: Evergreen blue/grey-green lance leaves; smooth, mottled bark; tidy canopy
• Flowers: Showy, nectar-rich blooms mainly late autumn–spring; decorative gumnuts follow
  
• Seasonal Interest: Evergreen structure and bark interest year-round; peak flowering winter–spring
• Wildlife Value: High — honeyeaters, bees and other pollinators; canopy for shade/shelter
• Tolerance: Drought-tolerant (once established), heat-tolerant, wind-tolerant, second-line coastal-tolerant; frost hardy; clay-tolerant (with improved drainage)
• Planting Density: Avenue/specimen: 1 tree per 16–36 m² (4–6 m apart), depending on desired canopy
• Pet Friendly: No — toxic to pets (eucalypt oils); prevent chewing of leaves/pods

Where It Works Best

• Sunlight: Full sun (tolerates light part shade)
• Soil: Well-drained loam, sandy loam or clay loam; handles 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 wide; formative prune while young to a balanced frame (don’t top); remove deadwood as required; minimal feeding
• Lifespan: 50–100+ years
• Climate Zones: Suited to temperate and Mediterranean SA gardens, including coastal areas
• Soil pH: Acid, Neutral, Alkaline — broadly adaptable with drainage

Landscape & Design Ideas

• Feature or street/driveway tree with winter nectar for wildlife
• Avenue/shelterbelt on larger blocks (allow canopy space)
• Low-water native schemes with lomandra, westringia and eremophila
