Tasmannia lanceolata – Information Sheet

Tasmannia species are small trees with glossy, aromatic leaves, found in the cool mountainous regions of south-eastern Australia. The genus is significant since it contains some of the most pungent or hot tasting species found in the native flora. P. lanceolata has become a popular “bush food” item due to its spicy flavour. It has much potential as an antimicrobial and antifungal medicine; the compound polygodial having been proven to be a potent inhibitor of Candida albicans and other pathogenic organisms. A close relative - Drimys winteri - from South America - is the source of Winter’s bark, once used as a specific against scurvy on long ocean voyages. Mountain pepper is a multi-purpose plant, and suitable for cultivation in cooler, high-rainfall areas.

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.
