The Australian Finger Lime Tree

Buy Australian Finger Lime Tree

Australian Fingers Limes, also called citrus caviar, are a unique looking citrus. Finger limes can come in an assortment of colors. The ones most commonly sold in America are green.

These trees tend to perform best in environments similar to where they are found in Australia. Oddly enough, these trees can tolerate less sunshine than most other citrus trees. This is because natively these are found in the understory of canopies. They’ll likely do best in very hot, less humid environments like southern California rather than Florida. Nevertheless, these trees can be grown indoors with success.
