The finger lime tree produces small but unique citrus fruits that are packed with flavor and juice. These fruits can come in various colors, including green, yellow, pink, and magenta, and contain numerous tiny juice vesicles, giving them a caviar-like texture. With a simple care routine, it's easy to bring the finger lime tree to harvest. This species of citrus is known for its hardiness and adaptability, making it an excellent choice for gardeners looking to grow something a bit more exotic. One of the most remarkable features of the finger lime tree is its versatility. It can grow as a dense hedge, a small tree, or even a manageable container species, depending on your preference and gardening goals. The Australian finger lime is a native citrus variety that is found growing as an understory shrub or tree in the rainforests of Southeast Queensland and Northern New South Wales. It blooms in the fall with white to light pink blossoms that give way to finger-shaped fruit that is about 5 in. (12 cm) long. To grow Australian finger limes, it's best to start with grafted stock or semi-hardwood cuttings, as these will produce hardier and more rapid-growing trees. The soil should be rich in organic matter and slightly acidic, and the tree should be situated in dappled sunlight to full sun.
