Hymenosporum Flavum

Native Frangipani / Queensland Frangipani

Botanical Name: Hymenosporum flavum
Family: Pittosporaceae
Origin: Eastern Australia (NSW–QLD rainforests) & New Guinea

Overview

Hymenosporum flavum (Native Frangipani) brings instant romance to South Australian gardens. A neat, evergreen canopy carries highly perfumed tubular flowers that open cream and age to butter yellow in spring–early summer, filling courtyards and patios with scent. Tough once established, it’s ideal as a feature, screen or avenue tree in coastal and Mediterranean climates.

• Mature Size: 6–10 m H × 3–5 m W (can be kept 3–5 m with pruning)
• Growth Rate: 40-80 cm per year under good conditions
• Foliage: Evergreen, glossy deep-green leaves; new growth often bronze; dense, tidy canopy
• Flowers: Masses of fragrant cream → yellow, starry/tubular blooms in spring–early summer; decorative pods follow
  
• Seasonal Interest: Year-round structure; peak spring–summer colour and fragrance; pods late summer–autumn
• Wildlife Value: Nectar for bees and butterflies; shelter for small birds
• Tolerance: Drought-tolerant (once established), heat-tolerant, wind-tolerant, second-line coastal-tolerant; light frost (protect young plants)
• Planting Density: Avenue/specimen: 1 tree per 9–16 m² (3–4 m apart); screening: 2–3 m apart
• Pet Friendly: Yes — not known to be toxic to cats/dogs; discourage chewing

Where It Works Best

• Sunlight: Full sun to part shade
• Soil: Well-drained sandy loam to loam; tolerates clay-loam if drainage is improved
• 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; light prune after flowering to shape; fertilise in early spring with a balanced slow-release
• Lifespan: 25–40+ years
• Climate Zones: Suited to temperate and Mediterranean SA gardens, including coastal areas
• Soil pH: Slightly acidic to neutral

Landscape & Design Ideas

• Perfumed feature near windows, patios and entryways for evening fragrance
• Evergreen screening/hedging along boundaries; clip lightly after flowering for a refined finish
• Avenue or courtyard specimen; underplant with shade-tolerant natives (Dianella, Lomandra) for a lush, low-care layer
