Description
It has an erect and spreading habit, growing to 1.5 m (5 ft) in height. Young branches are covered by short white hairs, but these are lost with age. The leaves are about 25 mm (1 in) long, and deeply divided into three narrow segments, each of which is typically further divided into two laciniae. Thus most leaves have 6 laciniae, though sometimes there are 8, and very rarely fewer than six. Each lacinia is about 3 mm wide, somewhat concave, with a linear margin.
The single red flowers appear in September and October and again in March.[ It has a similar appearance to '']Adenanthos sericeus

Cultivation
Albany woollybush is grown for its silvery foliage, rather than its relatively insignificant flowers, though the latter produce copious nectar that attracts honeyeaters.
Although it is from a dry summer climate, it adapts to humid summer conditions.[ It prefers a position in full sun or part shade and freely draining light soil.][ Plants can be propagated relatively easily from cuttings of semi-mature current season's growth.][
