Finger lime is a native Australian rainforest citrus prized for its caviar-like juice vesicles and intense citrus flavour. It is native to the subtropical and warm temperate rainforests of southeast Queensland and northern NSW but adapts well across a broad range of Australian climates. Tracked varieties include Sunshine Yellow and Wauchope, plus various colour forms ranging from green to red to black skin and pink, yellow, or clear flesh. Finger lime grows as a dense, thorny shrub or small tree. It tolerates shade but produces heavier crops in full sun. Soil must be free-draining; finger lime dislikes waterlogged conditions. Fertilise lightly with a citrus-specific fertiliser during the growing season. Trees are slow-growing and may take 5-7 years from seed to first fruit. Grafted trees fruit in 2-3 years. Fruit is typically ready from autumn through winter. In WA, finger lime is increasingly grown commercially and in home gardens. It is subject to standard citrus biosecurity protocols in WA, which restrict the importation of citrus plants from other states. Purchase only from certified WA-registered suppliers or those holding appropriate state permits. Armoured scale and bronze orange bug are the primary pests to monitor.
