The Australian finger lime tree, also known as Citrus australasica, is a unique and fascinating citrus tree native to the rainforests of Australia. It is a small evergreen tree with an upright growth habit, reaching a height of about 10 to 20 feet. The foliage consists of small, slender, and glossy dark green leaves.
 
What makes the Australian finger lime tree particularly remarkable is its fruit. The finger lime fruit is elongated and cylindrical, resembling a finger or a small cucumber. It typically measures around 2 to 4 inches (5 to 10 centimeters) in length. The skin of the fruit can vary in color, ranging from green to yellow, brown, or even purplish-black.
 
When the finger lime fruit is cut open, it reveals a treasure trove of tiny juice-filled pearls. These juice vesicles are similar in appearance to caviar and vary in color, usually ranging from translucent to pink, green, or yellow. Each vesicle bursts with tangy, citrusy flavor when bitten into, offering a unique and refreshing taste experience.
 
The Australian finger lime tree is highly valued for its distinctive fruit, which is often used as a gourmet ingredient in various culinary creations. It adds a delightful burst of flavor and texture to dishes, salads, desserts, and beverages. Additionally, the tree's ornamental qualities, with its slender leaves and unusual fruits, make it an attractive choice for home gardens and landscaping.
