Summary: It isn’t often gardeners get to hear the word “caviar” used in the context of a plant in their garden, but that is a valid association when one is talking about the unique citrus tree called finger lime. Right away, throw out everything you know about limes. Finger lime (Microcitrus australasica) is a small, shrubby and thorny tree native to the eastern coastal rain forest of Australia. Trees vary in height from 5 to 12 feet, with a spread of as much as 6 feet.
