Citrus australasica, commonly known as the Finger Lime or Caviar Lime, is an evergreen shrub grown for its unusual fruit, which is regarded as a food delicacy. The oblong fruit has caviar-like flesh, which is juicy with a tangy, lemon-lime flavour. Citrus australasica typically grows to 2 m tall and the same wide, and can be pruned as necessary. The trees are commonly added to a mixed planting, planted around outdoor living areas, maintained in containers, or grown as small specimens.

What Makes Citrus australasica Special?

Finger Lime’s appeal lies in its remarkable fruit. Each Australian finger lime tree produces cylindrical fruit with a tough skin and a riot of coloured pulp—ranging from pale pink to green, red, or even yellow. Slice open a finger lime, and you'll find hundreds of bead-like juice vesicles bursting with tart, aromatic flavour. These “caviar” pearls are perfect for garnishing seafood, cocktails, desserts, and salads, and have become a prized ingredient in modern cuisine. The tree itself is compact and bushy—ideal for hedging, container growing, or even as a decorative specimen in smaller spaces.

Growing an Australian Finger Lime Tree in New Zealand

Finger limes are surprisingly adaptable and can thrive across many parts of New Zealand with a bit of care. Choose a sunny, sheltered spot with well-drained soil to plant your Australian finger lime tree. Protect young trees from frost and wind, and mulch generously to retain moisture and suppress weeds. Regular feeding and deep watering will help your tree grow strong and healthy. Finger limes are self-fertile but benefit from the presence of other citrus, such as Citrus junos, Kumquat 'Meiwa' (Cumquat Meiwa), or Lime Tahitian, for improved pollination and fruit set.

Uses for Finger Lime Fruit

The Australian finger lime tree offers more than just visual appeal. Its fruit is a star among foodies, beloved for the tart “pop” of each caviar bead. Use them to dress up raw oysters, add zesty flavour to salads and ceviche, or elevate desserts and drinks. The tree is also a great choice for edible gardens, urban growers, or citrus enthusiasts wanting something truly different. Consider pairing finger limes with other unique citrus like Citrus medica sarcodactylis or Citrus Ugli Fruit to expand your collection with rare and fascinating fruit.

Choosing Citrus Companions and Rootstock

Finger lime trees can be grafted onto various Citrus Rootstock for improved vigour and resilience. If you want to explore more unusual citrus, try planting alongside Citrus Flying Dragon or Orange 'Tarocco' for a dynamic citrus garden.
