Propagation
Sow fresh seed during early spring and pre-soak seeds in heated water 13º to 18ºC (55º to 64ºF) for 24 hours. Seeds may require scarification.

Root, stem (use vertical stems) or limb cuttings during the growing period. 

Note
It is strikingly beautiful tree but care should be taken as the roots are invasive and can cause structural damage to roads, walls and pathways particularly in drier regions.

Botanic information
Leaf: The bipinnate leaves have 2-6 pairs of elliptical to obovate leaflets that are up to 15mm (⅝in) long and are glossy green above and grey and pubescent on the underside. 

The terminal leaflets are up to 65mm (2½in) long and turn yellowish before falling. The leaflets fold up during night on a hinged petiole to reduce evaporation and reopen during daylight to photosynthesise.

Flower: The small funnelform flowers have long white based stamens that are red-pink towards the end and are in bundles of 8-10. They are arranged in umbel-like cluster that is up to 15mm (⅝ in) wide on a pubescent peduncle, up to 30mm (1⅛in) long and appear during spring.

Fruit: The dehiscent long flat legume is constricted and partitioned between the seeds which are embedded in a sweet pulp. The green pod turns black when ripe and is editable and is sometimes used for cattle fodder. The seeds are viable but the plant may be reproduced vegetatively.
