General Description:

The genus Boronia is one of the best known of all Australian plants. There are approximately 95 species, all but one of which occur only in Australia. The majority of species are found in south-western Australia.

Boronia serrulata is a small, shrub of up to 1 metre in height and width. The leaves are rhomboid in shape, tapering towards the stem.  They are crowded against the stem and about 15 mm long by about 10 mm wide.  Like other boronias, the leaves have a strong odour when crushed. The perfumed flowers are 4-petalled of a star-like appearance and bright pink in colour. They are well displayed towards the ends of the branches, are up to 10 mm in diameter and are seen from late winter to spring.

This species has been in cultivation for many years and is a very desirable garden plant. However, in common with many other boronias it can be difficult to maintain for long periods in cultivation. It requires a well drained moist soil, preferably in semi shade. It should not be allowed to dry out.

In common with most members of the Rutaceae, propagation of B.serrulata from seed is difficult. Propagation from cuttings of current season’s growth can be slow to strike.
