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.
B.safrolifera is a small shrub of up to 1 metre in height and is usually found in moist, protected areas. The flowers are 4-petalled of a star-like appearance and are pale to deep pink in colour. They appear in spring and are well displayed in the upper leaf axils and are about 10mm in diameter. The foliage is pinnate (compound leaves made up of a number of leaflets) with leaves to around 35 mm long.
This species has been in cultivation for many years and is a very desirable garden plant. Like 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.safrolifera from seed is difficult but cuttings usually strike readily from current season’s growth.
