Finger Lime

Citrus australasica | Unique finger-shaped citrus with tangy flavour bursts

The Finger Lime is a fascinating and highly sought-after citrus variety native to Australia, prized for its unusual elongated fruit filled with tiny juice-filled pearls often referred to as “citrus caviar”. When squeezed, these vibrant pearls burst with a refreshing tangy flavour, making them a favourite among chefs and food enthusiasts. With its dense evergreen foliage, ornamental appearance and distinctive fruit, the Finger Lime is both a productive edible plant and a striking garden feature.

Plant Care

Sun: Full sun to light partial shade. In hotter regions, some afternoon shade can help protect foliage during extreme summer heat.

Soil: Prefers fertile, well-drained soil rich in organic matter. Avoid heavy clay soils that remain wet for extended periods.

Water: Moderate — keep soil evenly moist, especially while establishing and during fruit development. Avoid prolonged waterlogging.

Fertiliser: Feed regularly with a balanced citrus fertiliser from spring through late summer. Supplement with micronutrients if needed to maintain healthy foliage.

Pruning: Light pruning after harvest helps maintain shape and encourages dense growth. Remove dead, damaged or overcrowded branches as required.

Top tip: Finger Limes naturally grow as dense, thorny shrubs. Regular light pruning can improve airflow, make harvesting easier and encourage a more compact growth habit.
