Origin of Scientific Name

Boronia – after Francesco Borone, 18th century Italian botanist.

crenulata – (Latin) crenulated or finely scalloped, referring to leaves.


Boronia crenulata is a dense, dwarf shrub found predominately in the south-west of Western Australia from the Esperance Plains to the Swan Coastal Plain growing in a wide range of soils.

It grows up to 1 m high and 1 m wide with upright branches and small light green spoon-shaped leaves. These leaves have a high oil content and smell like aniseed, hence the common name of Aniseed Boronia.

The Aniseed Boronia produces masses of small pink and open-petalled flowers from July to December. It is a very ornamental species, which has adapted well to cultivation, varying in foliage colour and form.

Horticultural tips

  • Grows in a range of soils in dappled shade to part-sun.
  • Requires well-drained soil with plenty of humus that does not dry out readily.
  • Performs well in pots.
  • Prune lightly after flowering to encourage new growth.
