Australian Finger Lime Tree – Rare Citrus, Big Flavor, Easy Growth

Looking for a citrus tree that truly stands out? The Australian Finger Lime Tree delivers on every front — from its extraordinary, pearl-filled fruit (known as “citrus caviar”) to its tough, no-fuss growth habit.

Native to the rugged coastal rainforests of Australia, this compact citrus is built to thrive. Whether you’re working with a small backyard, a patio container, or an open garden bed, the Finger Lime fits right in — and pumps out gourmet fruit like a pro.

Why You'll Love the Australian Finger Lime Tree

• Citrus Caviar Fruit: Long, slender limes filled with tiny, pearl-like juice vesicles that burst with bright, zesty flavor — a favorite of chefs and food lovers alike
• High Yield, Low Effort: Vigorous and productive even with minimal care
• Cold-Tolerant: One of the hardiest citrus varieties — handles light frosts and cooler temps better than most
• Compact & Container-Friendly: Ideal for small spaces, patios, balconies, or urban gardens
• Naturally Low-Maintenance: Adapted to tough conditions with minimal upkeep needed
• Ornamental Appeal: Attractive, fine-textured foliage and a graceful form make it a standout in any landscape

Growing Zones & Care Guide

• USDA Hardiness Zones: Best planted in the ground in Zones 8–11. The Australian Finger Lime is one of the most cold-hardy citrus species, tolerating brief dips to around 22°F (−28°C) once established.
• Zones 4–7 (Container Growing): Grow in a 15–25 gallon container and move indoors before hard frost. A bright window or grow light will keep it healthy through winter.
• Sunlight: Full sun preferred — 6–8 hours daily. Tolerates partial shade but produces best fruit in full sun.
• Watering: Allow the top 2–3 inches of soil to dry between waterings. Drought-tolerant once established; avoid overwatering.
• Soil: Well-draining, slightly acidic soil (pH 6.0–7.0). Sandy loam or citrus potting mix works well.
• Fertilizing: Apply a citrus-formulated fertilizer in spring and summer. Light feeding in early fall; none in winter.
• Harvest Window: Late summer through winter (August–January), depending on your climate and variety.
