(Vickery) Craven & Biffen
The ringwood tree has a dense crown and grows up to 45 metres tall. The leaves are 6–12 cm long with prominently undulate margins and rich aniseed aroma when crushed.
Flowers are white and sweetly scented, borne in panicles. The fruit are dry papery capsules around 5 mm long and are white in appearance.
Used as a flavouring spice and herbal tea ingredient. Although previously known, it was first sold in the early 1990s as a bushfood spice, and in the mid 1990s cultivated in plantations to meet demand.
'Aniseed myrtle' is the name originally coined to specifically describe high quality selections of the trans-anethole chemotype (90%+) - generally recognized as safe for flavouring. These selections are propagated from cutting for consistent essential oil quality. The aniseed myrtle selections are also low in methyl chavicol and cis-anethole (less than 0.1%).
A significant fungal pathogen, myrtle rust (Uredo rangelii), was detected in aniseed myrtle plantations in January 2011. Myrtle rust severely damages new growth and threatens aniseed myrtle production. Controls are being developed.
