Small to medium southeastern Australian native she-oak with strongly drooping weeping foliage and dark furrowed bark. A tough drought- and frost-tolerant inland windbreak across southern Australia.
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 | 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
- Distinct from the related black she-oak Allocasuarina littoralis (already in the database as `allocasuarina`) — drooping she-oak has more strongly pendulous foliage and a wider drier climate range
- Drought tolerant, frost tolerant, lime tolerant — succeeds across a wider environmental range than most she-oaks, including the southern Australian wheat belt
- Fixes nitrogen via actinorhizal Frankia bacteria in root nodules — improves poor soils
- Major host plant for the endangered glossy black-cockatoo (Calyptorhynchus lathami), which feeds almost exclusively on the cones — a key conservation planting in southeastern Australia
