The Gold Standard of Indoor Citrus. Known as the Tahiti or Bears Lime, the Persian Lime is the most popular variety in the United States for good reason. This elegant bonsai produces fruit approximately 6 cm in diameter with a smooth, green rind and a refined, less-acidic flavor. Unlike other citrus varieties, the Persian Lime is virtually thornless and seedless, making it a joy to prune and maintain. Its ability to thrive in indoor environments makes it the perfect living centerpiece for your home.
