Propagation
Sow fresh seed during spring in pots and place in a cold frame to germinate in cool climates.

Take soft tip cuttings of non-flowering shoots during the growing period.

Note:
This tree contains saponin, which is found in many parts including the stem, branches, roots and in the walls of the fruit. It was used by the Australian aboriginals as a poison to stun fish.

Botanic information
Leaf: The pinnate leaves have 12 to 18 lanceolate leaflets that are slightly pubescent and almost sessile and an acuminate apex. The leaflets arranged oppositely along the rachis and juvenile leaves can be bipinnate. Rachis, petiole and stems are covered in brown fur.

Flower: The tiny flowers are arranged in a small panicle that appears during early spring. The flowers are not regarded as a feature of the plant. 

Fruit: The capsule is covered densely in fine, sharp hairs that can cause skin irritation. It is egg-shape with 3-lobes and contains 3-cells each with one dark brown seed that is up to 3mm (⅛in) long. The seeds are viable but the plant may be reproduced vegetatively.
