Growing notes
- Endemic to a tiny native range in southern NSW around Cootamundra and the Riverina
- WARNING: Listed INVASIVE outside its native range — across much of Australia (Victoria, Tasmania, WA, SA), California, and South Africa; widely planted before its invasiveness was understood, do not plant outside its small native NSW range
- Purple-foliaged cultivar ‘Purpurea’ is widely sold and equally invasive
- Nitrogen-fixing legume — fixes nitrogen via Rhizobium
