Australian Finger Lime

Description

Australian Finger Lime is one of those plants that feels like a secret ingredient growing on a tree. Instead of typical citrus segments, the fruit is filled with tiny, bead-like juice vesicles—often called “citrus caviar”—that pop with bright, aromatic acidity.

This green selection is grown primarily for culinary use: slicing and squeezing over seafood, tacos, salads, desserts, and cocktails where you want a clean citrus lift and an unforgettable texture. The tree stays naturally compact and does very well in containers, making it a favorite for patio growers and chefs alike.

Overview

• Green finger lime with “citrus caviar” pearls for garnish and finishing.
• Bright, aromatic flavor with a clean lime-like snap.
• Compact, container-friendly growth habit.
• Soft thorns are normal—handle with care when pruning and harvesting.
• Self-fertile.

Growing Details

Latin Name: Citrus australasica

Site and Soil: Full sun; well-drained soil

Rootstock: 1-gallon trees on Flying Dragon; larger sizes on C-35

Hardiness: Frost sensitive; protect from freezing temperatures—mature trees may tolerate brief dips into the upper 20s°F, but protection is recommended below 32°F

Bearing Age: Often fruits immediately; grafted trees may produce in their first season

Size at Maturity:

• Flying Dragon: Typically 6–8 ft tall and wide

• C-35: Typically 10–12 ft tall and wide

Note: Trees grown in containers remain smaller and are easily maintained with pruning.

Bloom Time: Spring to early summer

Ripening Time: Fall to winter (timing varies by climate and growing conditions)

Pollination Requirements: Self-fertile

Pests & Diseases: Similar to other citrus; good airflow and excellent drainage reduce issues

Additional Notes

• Grower’s Insight: The “caviar” texture is the magic—slice the fruit crosswise and let the pearls tumble out as a finishing garnish.
• Regional Insight: Best suited to mild-winter regions; in cooler climates it excels in containers so you can protect it during cold snaps.
• Harvest tip: Finger limes don’t always drop when ripe—pick when the fruit feels full and releases with a gentle twist.
