Among the tallest hardwoods in the world, reaching 90 m, with smooth shedding bark mottled cream and pink. Pale, strong, dense timber used for structural beams, flooring, and panelling.
Hardiness ratings
| System | Rating | Temperature range | How to read it |
|---|---|---|---|
| USDA hardiness zone | Zone 9–11 | −6.7 °C to 10 °C | Plant tolerates down to this zone |
| RHS hardiness rating | H3 | −5 °C to 1 °C | Plant needs at least this level of cold tolerance |
| Canadian plant hardiness zone | Zone 9 | −1 °C and warmer | Plant tolerates down to this zone |
| Australian (ANBG) zone | Zone 3–7 | −5 °C and warmer | Plant tolerates down to this zone |
Growing notes
- Heartwood — pale pinkish, dense, very strong, used for structural beams, flooring, joinery, and historically for railway sleepers and ships’ keels
- Among the tallest hardwoods in the world — only mountain ash (E. regnans) and coast redwood exceed it
- Smooth shedding bark mottled cream, pink, and grey — strikingly photogenic, a major draw of the southwestern WA forests
- Endemic to southwestern Western Australia — does not grow naturally outside a small area between Manjimup and Walpole
- Not reliably hardy outdoors in Canada — Canadian zone values shown represent the system maximum and do not imply garden cultivation north of the warmest coastal pockets.
