Summary:
The finger lime is an Australian native citrus that is tolerant to huanglongbing (HLB), and it has been gaining popularity and significance in recent years. This fruit has several unique qualities that distinguish it from conventional sweet oranges and mandarins. The primary characteristic of finger limes is their round to teardrop-shaped juice vesicles, which burst when the fruit is cut. These juice vesicles are commonly referred to as citrus caviar, and they are the main product in commercial trade. The UF/IFAS citrus improvement program has released two improved finger lime hybrid cultivars for Florida growers to cultivate as specialty crops. The UF SunLime is a finger lime hybrid that produces cylindrical fruit averaging about 3 inches in length. The UF RedLime, on the other hand, is narrow and oblong in shape, tapering slightly at both ends, with lengths ranging from 3.5 to 5 inches. Under central Florida conditions, both cultivars produce high levels of anthocyanins in the juice vesicles and skin. Locally grown finger limes can be a valuable addition to the Fresh from Florida portfolio, helping to strengthen local food systems and leading to increased sales for restaurants and businesses
