Boronia crenulata

Aniseed Boronia

With its masses of star-shaped flowers, Boronia crenulata makes a statement in any garden.

Boronia crenulata is a dense, small shrub growing up to 1 m high. It is an ornamental species that is suitable for growing in the garden or in a medium-sized pot, with pink-purple flowers from winter through to early summer.

Aniseed Boronia will grow in a range of soils in dappled shade to part-sun. It needs well-drained soil with plenty of humus that does not dry out readily. Choose a sheltered site to protect the plant from hot afternoon sun in summer.

Grow it at home

  • Plant from late autumn to early spring
  • Apply a slow-release native plant fertiliser at the time of planting then annually after pruning
  • Water Boronia crenulata in well at time of planting and monitor its water needs ensuring it neither dries out nor becomes water-logged
  • Apply a loose mulch to assist in water retention
  • Prune lightly after flowering to encourage new growth and maintain shape

The common name of Aniseed Boronia comes from the leaves, which have high oil content and smell like aniseed when crushed.
