Australian Finger Lime Tree

Australian Finger Lime Tree

Australian Finger Lime Tree is one of the most fascinating discoveries in our fruit world. This unusual variety is sometimes called Citrus Caviar. Contained in the dark purple, 3″ long fruit are a multitude of juicy capsules bursting with intense, sweet-tart, lemon-lime flavor. Found in the wild in Australia, Finger Limes have only recently been introduced to the US.
