Boronia crenulata is naturally found in south-west Western Australia growing in a variety of habitats that included the margins of swamps or watercourses and woodlands from sea level to an altitude of 331 m (1092 ft). 

It prefers an open sunny position and grows in well-drained moderately fertile white to grey sandy or clay loams and gravelly soils that are tending acidic and is drought and mildly frost tolerant.
 
The Aniseed Boronia is grown for its bushy habit and flowers. It is planted in small or native gardens as a specimen or along borders or in rockeries and is grown in containers. It is suitable for coastal and inland regions establishing in 2-3 years but may be short lived. The variable shrub is also suitable for planting around watercourses or in swampy areas. ID 3302
