The Aniseed Myrtle
Ornamental tree also grown for its oil and scented foliage. Backhousia anisata or Aniseed Myrtle. Known known as Syzgium anisatum and previously as Anetholea anisata it is still found under these names on occasions.
This is a hardy evergreen tree to around 10m ( much larger in its native rainforest habitat) prefers a humus rich moist soil. Creamy white flowers in spring.
Foliage is an attractive apple green and glossy, the leaves are slightly undulating or rippled creating a softer effect in the garden. It is from the foliage that the essentail oil is extracted and it does have an aroma very comparable with that of the true aniseed.
Flowers are a creamy white and fluffy with again an aniseed fragrance that attracts bees and other insects to the garden.
How To Grow Backhousia anisata
This is a tree that finds its natural habitat in sheltered areas along streams in the rainforest areas of New South Wales.
It will tolerate full sun, however performs best when protected from from very hot afternoon sun especially in drier soils.
Prune immediately after flowering leaving some foliage on each branch or stem. Regular pruning will keep the plant in a smaller and bushier shape.

If pruned from a young age it can make an excellent aromatic screening plant or hedge in the right conditions.
