The finger lime plant, also known as the caviar lime plant or citrus australasica, is native to the Queensland and New South Wales regions of Australia. The elongated, finger-shaped fruits contain tiny globe-shaped vescicles, or pearls, that add bursts of effervescent, tangy flavor and stunning visual pop to many dishes. Popping up (see what I did there?) in Antipodean restaurants in the early 2000s, finger limes are relatively new to the exotic fruit scene. Finger limes are a great source of vitamin C (supposedly three times than that found in mandarins), vitamin E, folic acid and potassium.
Fun Fact: Through hybridization, they come in a range of colors from the lightest pinks to the deepest blue-greens. This makes them, out of all citrus plants, This possibly gives them the honor of having the most broad range of pulp colors among all citrus.

Growing & Caring for

Your Finger Lime Plant

Growing a finger lime from seed can be excruciatingly slow, as it can takes 15 years! Growing from a cutting is also slow and difficult, so the preferred method of propagation is grafting onto rootstock.
