Growing notes
- Endemic to southwestern Western Australia despite the common Sydney name — the name is from the cut-flower trade rather than the natural range
- Major commercial cut flower — the showy pink-flowered boronia of florist shops worldwide
- Demanding cultivation — sharp drainage, cool root run, Mediterranean climate; struggles in eastern Australian humid summers
- Less fragrant than brown boronia (B. megastigma) but more visually showy
