Finger Lime & Native Citrus
Citrus australasica, known worldwide as "citrus caviar" for its distinctive pearl-like juice vesicles. Australia's native citrus species command premium prices in global gourmet markets.
A uniquely Australian export
Australia is home to six native citrus species found nowhere else in the world. Indigenous to the rainforests of the Queensland-NSW border region, these species have been used by Aboriginal Australians for thousands of years.
Today, finger limes have captured the attention of chefs and food enthusiasts globally. The distinctive "caviar" pearls burst with intense citrus flavour, making them prized in restaurants from Tokyo to New York.
With growing international demand and limited supply, Australian growers have a significant opportunity to expand production of this premium native fruit.
The propagation challenge: Unlike many citrus species, finger lime is monoembryonic—meaning seeds do not produce true-to-type offspring. Each seedling is genetically unique, resulting in unpredictable fruit characteristics.
Species
Desert lime
Citrus glauca is native to the semi-arid regions of Queensland, New South Wales, and South Australia. Unlike finger lime, it is highly drought-tolerant and suited to cultivation where other citrus cannot grow.
The small fruits have a distinctive tangy flavour used in preserves, sauces, and beverages. Growing interest from the bush food industry is creating demand for quality planting material of selected varieties.
Tissue culture supports this emerging industry by enabling propagation of selected varieties with desirable fruit characteristics and tree form.
