Finger limes are a citrus fruit native to Australia but are now grown in North America. They are small and elongated, almost resembling gherkins, containing tiny spherical vessels filled with tart juice, sometimes called citrus caviar.
Finger lime trees aren’t ubiquitous. They can grow up to five metres tall in shady places and are most often found in Queensland and New South Wales rainforests. In other parts of Australia, you can grow finger lime trees.
