Sale price$5,400.00

Angophora costata – Sydney Red Gum is a striking, large Australian native tree renowned for its smooth, mottled bark and expansive canopy. Reaching heights of 20–30 metres, it makes a dramatic impact in parks, rural properties, and large gardens. The bark sheds in irregular patches to reveal stunning tones of pink, orange, and red—one of the most visually distinctive traits of Angophora costata – Sydney Red Gum.

Its dense, spreading crown of broad, lance-shaped green leaves offers ample shade, while the profusion of white flowers in late spring to early summer supports birds, bees, and pollinators. Hardy and drought-tolerant once established, Angophora costata – Sydney Red Gum thrives in coastal areas, poor soils, and full sun with minimal maintenance.

Whether used for habitat planting or as a stand-alone specimen, it looks excellent in large-scale landscapes, combining visual appeal with ecological resilience.
