Australian Round Lime A citrus species native to Queensland, Australia, the Australian Round Lime produces a lime fruit that has a flavor similar to a typical Bears lime, but with a little something different. The juice made from it is quite delicious and we have aspirations of making a Round Lime margarita someday! Plants are quite drought tolerant and grow into a large shrub over time, or can easily be kept in a pot and grown as a houseplant. Click here to view our Citrus Growing Guide.
