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 Are Finger Limes?

Finger limes belong to the species Citrus australasica and are often nicknamed “caviar lime” for their unique interior. Unlike traditional citrus fruits, finger limes have tiny, bead-like pulp vesicles that pop when bitten. These native bushfoods thrive in well-drained soil and warm, sheltered conditions and can even be grown in pots, making them a practical choice for smaller gardens or patios alongside other citrus favourites like Lime Sublime and Mandarin 'Miho'.

Popular Finger Lime Varieties

One of the most exciting aspects of growing finger limes is exploring the array of finger lime varieties now available in New Zealand. Each variety boasts its own distinctive skin and pulp colour, ranging from green and yellow to pink, red, and even black. Popular varieties include:

Mix and match different finger lime varieties to add contrast and creativity to your culinary and garden endeavours.

Growing Finger Limes in New Zealand

Finger limes are ideal for gardeners seeking something different to complement their citrus collection. Provide them with a location that offers full sun and protection from cold winds. Use a high-quality, free-draining soil, and keep an eye out for pests and diseases that may affect other citrus, like Citrus Flying Dragon or Citrus junos. For best results, you may want to graft your finger lime onto a suitable Citrus Rootstock to ensure vigour and productivity.

When planning your home orchard, finger limes sit beautifully alongside more traditional choices, such as Orange 'Franklin Navel' or the aromatic Citrus medica sarcodactylis, and add a unique element to the landscape.

Unique Relatives and Other Citrus Curiosities

Curious gardeners might also explore unusual relatives and other exotic citrus, including the fascinating Citrus Ugli Fruit or the spicy-sour Lime Rangpur. Experimenting with finger lime varieties and their cousins opens up a wealth of flavours and aromas, ideal for adventurous home cooks looking to extend their kitchen creativity and garden diversity.

Grow your very own finger lime and discover why these unique varieties are taking centre stage in gardens and gourmet kitchens across New Zealand.
