WHAT IT LOOKS LIKE:

1. Spreading rounded shrub growing 1–4 m high and wide

2. Branchlets yellow or reddish, minutely hairy

3. ‘Leaves’ grey-green, 1.5–5 cm long, 3–7 mm wide, radiating around branchlets, variable in shape

5. Seed pods straight or curved, 5–10 cm long, 4–9 mm wide, dark brown at maturity, may have a whitish bloom
Typically it is a medium sized shrub about 2 metres high by a similar spread, but can occur as a shrub or tree 1- 12 m tall.
Leaves are up to 60mm long and 3 to 13mm wide. Upper surface is dark green with the lower surface white and hairy, appearing silvery in the wind. Small serrations may be found on the leaf edges and tips.
The pale yellow flowers are arranged in pairs and densely packed in cylindrical spikes which are up to 100mm long. Old spikes may persist on the plant.
The seeds are enclosed in follicles attached to a woody cone.
Flowers can occur throughout the year, but mainly February to July. The seed ripens from February to April, and is indicated by the wood hardening and the follicle colour changing to dark brown.

WHERE IT GROWS & WHY:

Hardy, fairly fast growing and long lived species.
Favours a sunny or partly shady position, and may become spindly if grown in the shade.
Tolerates a variety of soil types including sandy soils, loams and clay.
Prefers well-drained soils, but can tolerate moist and even waterlogged sites.
Drought resistant and will do well in exposed windy locations.

MANAGEMENT/SIGNIFICANCE:

Requires low maintenance, and hold their shape very well.
Some forms have a lignotuber, which is a woody swelling at the stem base that regenerates after fire.
Lignotuberous plants can be pruned hard, whereas non-lignotuberous plants should only be lightly pruned.
