Eastern Australian coastal native casuarina. Critical food plant for the glossy black cockatoo, which feeds almost exclusively on its seeds.
Hardiness ratings
| System | Rating | Temperature range | How to read it |
|---|---|---|---|
| USDA hardiness zone | Zone 8–11 | −12.2 °C to 10 °C | Plant tolerates down to this zone |
| RHS hardiness rating | H4 | −10 °C to −5 °C | Plant needs at least this level of cold tolerance |
| Canadian plant hardiness zone | Zone 8–9 | −7 °C and warmer | Plant tolerates down to this zone |
| Australian (ANBG) zone | Zone 4–7 | 0 °C and warmer | Plant tolerates down to this zone |
Growing notes
- Fixes nitrogen via Frankia bacteria (actinorhizal symbiosis) rather than the Rhizobium of legumes — a non-legume nitrogen fixer
- The glossy black cockatoo depends almost entirely on Allocasuarina seeds — planting this species directly supports a threatened species
- Drought tolerant once established
