Australian Red Finger Lime Tree
We’ve seen them from growers in Australia and lusted after them for years and now we finally have the red pulped Australian Finger Lime! The plant itself is essentially identical to the finger lime we’ve grown for years but the fruits have a reddish-green skin and when you crack them open the citrus caviar inside is a bright pink to red color with a slightly more fruity flavor than the typical finger lime.
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.
Latin Name: Microcitrus australasica
Site and Soil: In spring, summer and fall, keep your potted Citrus in a location with 1/2 day to full sun. In the winter, place your plant in a well-lit room. Potting soil should be coarse, acidic, and well-drained.
Rootstock Description: Flying Dragon is a hardy and very dwarfing rootstock for Citrus that induces very early flowering and fruit production. Trees grown on Flying Dragon will rarely exceed 5 ft. in height and will often produce fruit the year they are planted.
Pollination Requirements: Australian Finger Lime is self-fertile. You can help it set fruit by taking a small brush and moving pollen from flower to flower.
Hardiness: We recommend bringing Australian Finger Lime to a well-lit and protected location in early fall before frost.

Pests & Diseases: While outside, Citrus plants will likely not be bothered by insect pests. Be on the lookout for slugs. Indoors, Citrus can have mites and/or aphids. Watch carefully for any problems and treat with an insecticidal soap or wash them off. We have not seen any disease problems on our Citrus plants.
