Sapium Sebiferum

Chinese Tallow Tree

Botanical Name: Sapium sebiferum
Family: Euphorbiaceae
Origin: East Asia (China, Taiwan, Japan, Vietnam)
Plant Type: Deciduous tree

Overview

Sapium sebiferum (Chinese tallow) is a fast-growing, small to medium feature tree valued for brilliant autumn colour in South Australia. Heart-shaped leaves turn shades of yellow, orange and red, while spring catkins are modest but nectar-bearing.

Key Features

• Mature Size: 6–10 m H × 4–6 m W (rounded crown)
• Growth Rate: 40-80 cm per year under good conditions
• Foliage: Glossy, heart-shaped green leaves; spectacular red–orange–yellow autumn display
• Flowers: Inconspicuous yellow-green catkins in spring; 3-lobed capsules with white “tallow” seeds (remove to limit spread
  
• Seasonal Interest: Deciduous shade in summer; standout autumn colour; winter silhouette
• Wildlife Value: Catkins provide nectar/pollen for insects; seeds can be bird-dispersed—deadhead to reduce spread
• Tolerance: Heat and drought tolerant once established; tolerates periodic wet soils; light to moderate frost
• Planting Density: Feature/avenue: space 3–5 m apart
• Pet Friendly: No — milky sap is a skin/eye irritant; ingestion can be harmful

Where It Works Best

• Sunlight: Full sun (best colour) to light part shade
• Soil: Adaptable—well-drained loam to clay loam; handles occasional wet; avoid waterlogged sites near bushland (to prevent escape)
• 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; winter prune to shape; remove seed clusters before they mature; wear gloves when pruning (latex sap)
• Lifespan: 30-60+ years
• Climate Zones: Suited to temperate/Mediterranean SA sites; provide frost protection in colder Hills pockets
• Soil pH: Slightly acid to neutral; tolerates mildly alkaline soils

Landscape & Design Ideas

• Feature tree for striking autumn colour in medium/large gardens
• Avenue or driveway spacing at 3–5 m for seasonal canopy
• Shade for lawns/patios; avoid creeklines and natural areas to prevent spread
