Regeneration: |
From seed after disturbance such as fire. Colonises steep bare banks in shallow soils. Readily established when direct seeded. |
Timber: |
|
Shade and Shelter: |
Useful low-level cover in windbreaks in districts where known not to spread. |
Land Protection: |
Useful for controlling soil erosion due to soil-binding fibrous roots, and for improving soil fertility. Legume - improves soil fertility by 'fixing' nitrogen. |
Wildlife: |
Excellent habitat. Very useful refuge and nesting sites for small birds, such as wrens and thornbills due to prickliness. Flowers are a food source for moths, \ butterflies and other insects. Insect-eating birds attracted. Seeds eaten by native birds, including parrots and native pigeons. |

Attractive specimen for hedges, barriers, screening, tubs and as cut flower, for districts where it does not spread. Prune lightly after flowering to prevent straggly growth. Resents severe pruning. |
