Propagation
Pre soak the seeds overnight and scarify before sowing in containers during spring.

Take semi hardwood cuttings that are 50-60mm long during late summer. Some cultivars require layering or grafting onto a rootstock.
These plants dislike transplanting or root disturbance.

Note:
The young ridged stems remain green during winter, while older stems become brown. 

Botanic information
Leaf: The mid to dark green lower leaves are compound (trifoliolate) and upper leaves are simple (obcordate). The sessile ovoid buds are solitary and have 4-indistinct scales.

Flower: The red to yellow papillionate flowers are arranged in a raceme that appears on the older wood in the leaf axils from late spring to early summer.

Fruit: The slender downy pods are black when mature and crack open to release the seeds. The small seeds are viable but the plant may be reproduced vegetatively.
