- The leaves of this native myrtle, Backhousia anisata, have a strong aniseed flavour with a eucalyptus aftertaste. It is related to the lemon myrtle and grows in the coastal rain forest. The leaves are used either fresh or dried, whole or ground in meat dishes, desserts and baked goods. Since the essential oils are volatile, it is usually added just before service. The essential oil can be bought separately.
