Australian Finger Lime Tree

Availability: Out of stock

To say the Australian Caviar Finger Lime Tree (Citrus australasica) is not your typical Lime is an understatement. It looks nothing like a lime, in fact, some say it looks like a small pickle! Each fruit is a short, green cylinder shape that can be anywhere from 2 to 5 inches long.

Have you heard of Citrus caviar? The flesh of this Citrus-Lime variety isn't your standard, either. Instead, hundreds of round 'prills' literally spill out once the skin is cut into.

This unique fruit is where Australian Finger Lime gets its nickname, "the Caviar Lime." Each round little lime caviar 'prill' bursts in your mouth like a fine wine.

Enjoy how the intense lime flavor lingers on the back palate and lasts well into the next bite. Can you imagine the wonderful meals you'll season (and the yummy drinks you'll spritz) with these delicious little Lime pearls?

In addition to the wonderful taste, the small leaves and dainty flowers gave this plant a real ornamental appeal. Grow it as a shrub, a multi-trunk tree, or a single-trunked tree. This natural dwarf is a great indoor potted plant, as well.

Australian Caviar Finger Lime Tree is native to Australia and has only recently been discovered by the Citrus-loving masses worldwide. Although there are a number of different colors of Finger Limes such as yellow, pink, and red, only the green ones are currently available in the United States at this time.

Nature Hills is one of the few places where you can purchase this tree in the United States.

As you can imagine, these fabulous Citrus plants are in high demand. If its in stock, and you 'gotta have one', order it today! We will sell out fast!

#ProPlantTips for Care

If you live in a Zone where Citrus Trees thrive, then the Australian Caviar Finger Lime Tree is a good choice for growing in the ground on your property. If not, think about growing one in a container placed in a sunny window.

The Australian Finger Lime is one of the few Citrus or for that matter edible landscaping trees that can and needs to be grown in partial shade. Plant the Finger Lime where it gets plenty of morning sun and is entirely protected from the hot afternoon sun.

Traditionally grown as a bush or thicket, this is a great barrier plant as it does have thorns. Use this hard-working, valuable plant to protect your property in the right location.

The Australian Finger Lime is adapted to a wide range of soil and climates in Citrus-growing regions. Provide good drainage and regular water and increase the water during extreme heat periods. Citrus trees prefer acidic conditions and appreciate drying out slightly between waterings. Ensure container plants have adequate drainage holes and never sit in water for long. Set up a fertilizer routine to support your tree's growth.

Being an understory plant means it naturally grows beneath the canopies of tall Eucalyptus trees. The duff of the forest floor protects the plant's roots and provides nutrients. Provide a layer of mulch at least 3 to 4 inches deep and 3 to 4 feet beyond the outside of the canopy. This will help to keep the root system cool and nourished.

Protecting Container Citrus From Cold

The natural habitat of this Citrus variety would suggest it is a prime candidate for successfully growing and cropping in marginal Citrus areas. This is also true wherever Citrus trees are brought indoors during the wintertime.

If you're growing these tropical trees in the ground in the lowest of their favored growing zones, they need to be planted in a sheltered spot to avoid the worst of the chill. If a spot like that is unavailable then you are better off planting in a large, deep container.

In border-line growing zones, begin slowly acclimating your tree indoors or into a protected location, eventually moving your tree inside in bright indirect sun for the winter if the temperatures in your area ever dip below that 40F range. In spring, reverse this process and begin acclimating your tree to again be back out in the full sun all summer. This reduces stress and leaf drop.

Place it in a sunny greenhouse or sunroom in full sun for best results over winter. Keep it on the dry side, and supplement with grow lights if needed to keep the tree bearing fruit.

Savored Since Ancient Times

The native Aboriginal tribes have consumed the Australian Finger Lime for thousands of years. But it's only in the last 100 or so years that they become of commercial interest, and only since the 1980's have they become popular.

The Finger Lime is native to Australia where it grows in the rainforest of Southeast Queensland and Northern New Wales, located on the eastern seaboard of Australia. The plant is known as an understory plant because it grows under the shade of the forest canopy.

Used for thousands of years by the native Aboriginal population for both food and medicine, the Finger Limes were not considered that important by the original European colonial settlers. Quite often plants were plowed under to make way for farming, with only a select number being saved for fruit production.

First described and named by noted Australian botanist Ferdinand von Mueller in 1858, he originally called the Finger Lime Citrus australasica, and made the first reference to its commercial potential. In 1913 another noted Australian botanist, Frederick Manson Bailey identified a red-fleshed selection that came true from seed in the wild and called it Citrus australasica var. sanquinea.

It is noted that in 1915 the most famous citrus scientist of the time, Walter T. Swingle; while working for the USDA in Washington, DC., reclassified the Australian Finger Lime as a Microcitrus.

This reclassification recognizes the significant difference with true Citrus, of which the most important differences are the very small leaves and flowers, and the elongated fruit of the Finger Lime. It is reported that Swingle worked with the Finger Limes while in Washington, but the program never went any further.

Although there has been attempts to reverse this name reclassification, to date this has not happened, and the debate continues. It is however important to note that both Citrus australasica and Microcitrus australasica are both recognized and used interchangeably.

In more recent times, steady interest has grown in the United States, though the first establishment of Finger Limes in the States did not occur until 1966, when Dr. Joe Furr of the USDCS in Indio, California, sent budwood to UC Riverside.

Primarily recognized by the chefs and bartenders at first, the Finger Lime has now become a regular recommendation for the home garden. This is additionally supported by the fact that it is one of the few edible plants that will tolerate a partial day of shade. More recent adaptations show that it takes well to pruning, making it easy to control its size and is well-adapted to being espaliered.

In the future, the consumer can look forward to the many differently colored varieties of Finger Limes including pink, red, orange, yellow and of course the green that is available today.
