Boronia pinnata is a shrub reaching a height of 1.5 metres. The leaves are pinnate with 5-11 leaflets. The flowers are carried in clusters held in the upper leaf axils. Each flower is about 1.5 centimetres in diameter, four-petalled and pale to deep pink in colour. A white-flowered form is also in cultivation. Flowers are both conspicuous, profuse and appear in spring. Both foliage and flowers are strongly aromatic. Plants appreciate light pruning after flowering.
Boronia pinnata is hardy, free flowering and prefers well drained soils in semi-shade.
This attractive species occurs in all coastal areas and the central tablelands of New South and perhaps extending into southern Queensland.
