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
- Standard Australian native hedge and low windbreak — clips well, tolerates salt and wind, drought tolerant once established, virtually pest free
- Not related to true rosemary (Rosmarinus / Salvia rosmarinus) — Westringia is in the mint family Lamiaceae but the foliage and habit are similar
- Compact cultivars (‘Smokey’, ‘Mundi’, ‘Wynyabbie Gem’) cover almost every garden role from low edging to medium windbreak
- Flowers throughout the year in mild climates — useful continuous low-key bee forage
- 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.
