Lemon myrtle is an evergreen tree native to eastern Queensland. The fragrant lemon-scented leaves are rich in essential oils composed mainly of the terpene aldehyde, citral. Both the essential oil and phenolic compounds extracted from the leaves are potent antimicrobials and antioxidants. Lemon myrtle is widely used in aromatherapy and body care products and is in demand as a food flavour and beverage. Whilst easy to cultivate at home or in plantations, it has become susceptible to the introduced pathogen myrtle rust, which significantly impacts the yield and productivity in plantations.
Tetragonia tetragonoides – Information Sheet
Known as Warrigal greens and New Zealand spinach among other names, T. tetragonoides is a low growing, straggling herb whose bright green leaves are edible. It is a well-known coastal plant in Eastern Australia, but it also inhabits inland sites, and the distribution spreads into Asia as far north as Japan. Warrigal greens are quite nutritious, being high in iron and other minerals. The leaves also contain, oxalates, hence it is widely recommended they not be eaten raw. While there is little evidence T. tetragonoides was a significant edible or medicinal plant within Aboriginal communities, it does have a history of medicinal use in Japan and Korea. The plant is easy to propagate and grow, however it may need to be contained to prevent spreading.
