Behold the caviar of lime! This Australian Citrus tree is related to the Red Finger Lime and carries many similar qualities.  Their oblong Green Finger Lime fruits cascade translucent “citrus pearls” of vibrant green onto any tropical plate and into any citrus-lover’s heart. 

The free-flowing individual beads of citrus flesh are popular for gourmet dining, used for sour, bright, astringent toppings on any lime-loving hordevours. Native to sub-tropical rainforests of South-East Queensland, these sun-loving blasts of tangy flesh are loaded with tart flavor and minty fresh aroma. Traditionally considered a specialty crop “bush tucker”, the Green Finger Lime was rare and often merely foraged in the few places it was grown. Due to its uproar of popularity among chefs, an increase in tree production has grown the number of trees to reach demand. 

The Green Finger Limes grow best when kept out of wind and frost. They are nutrient hungry and grow well in pots, enjoying citrus-friendly soil amendments every 6 weeks during the growing season.

These thorny-branched trees are low maintenance for the most part and love to be pruned. Many growers will remove thorns near fruits to prevent punctures if blown by the wind (there’s your harvest hack of the day). 

Each thorn comes paired with an evergreen leaf at each axil. From these axils, you’ll find white-to-pink blossoms which will eventually become your virtually seedless fruit. You can keep your tree shrubby or let it grow up to its 25 ft. tall potential, either way, you’re sure to get a plentiful harvest!

Planting, cultural care, pruning, and harvesting are similar for all citrus plants, with a few slight variations. Generally, they are best planted in filtered sun with well-drained soil that can hold moisture and nutrients. Citrus trees a particularly high demand for nitrogen. If you’re fantasizing about long afternoons of picking fresh fruit from your personal citrus grove, keep this in mind: The key to growing citrus is setting it up for success from the start.
