Rare pink African tree blooms brightly in Moonee Valley

Visitors to the western side of the Moonee Valley Racecourse may have noticed a particularly eye‑catching tree coming into its own this season, the Calodendrum capense, commonly known as the Cape Chestnut.

This evergreen species, native to Southern Africa, is admired for spectacular floral displays and is one of the significant trees listed on Moonee Valley’s Significant Tree Register.

Although typically evergreen, the Cape Chestnut can behave differently in cooler climates, sometimes shedding its leaves. Most commonly recognised for its vibrant pink blossoms, the species occasionally produces rare white flowers. When in full bloom, its canopy becomes almost completely covered in flowers, creating a striking display that draws attention.

Arborists in Moonee Valley have recently observed that several Cape Chestnuts, particularly those receiving additional warmth from roadways, are now developing fruit. Historically, this fruiting has not been commonly seen in Melbourne’s cooler conditions.

This shift has prompted interesting questions among urban forestry specialists. As temperatures rise due to the urban heat island effect, species like Calodendrum capense may be responding in new ways. Arborists are continually monitoring these patterns as part of their work to identify resilient tree species suited to Melbourne’s future climate.

With its adaptability to a wide range of climates, from temperate through to tropical, the Cape Chestnut is becoming more popular across Melbourne. Although slow growing at first, the tree performs well when planted with proper soil preparation, mulching, and consistent watering.

Given adequate room to grow, the Cape Chestnut rewards with a broad, sculptural canopy and, in flowering season, a memorable display that has been stopping locals in their tracks.
