About Your New Angophora costata Sydney Red Gum

Angophora costata, the Sydney Red Gum, is one of Australia's most iconic native trees, instantly recognised by its smooth mottled bark that sheds in irregular patches to reveal striking tones of salmon-pink, orange, and copper-red.

Sydney Red Gum grows to 15-25 metres tall and 10-15 metres wide with a dense spreading crown of broad lance-shaped leaves that provides generous shade. The dramatic size suits parks, rural properties, and large gardens. Large clusters of white flowers appear from late spring into summer, supporting bees, lorikeets and honeyeaters.

Sydney Red Gum is hardy and drought tolerant once established, thriving in coastal areas, poor and sandy soils, and full sun across NSW and QLD. It tolerates light frost and works well as a habitat tree or a stand-alone specimen in large-scale landscapes.
