Native to north-western India, the Rangpur Lime is known by many other names around the world, including Mandarin Lime in the US and the Canton lemon in China. A fast growing citrus that is more cold tolerant than true limes, it’s a wonderful alternative for the cooler southern states and an excellent substitute in recipes. Often used as a rootstock for other, more sensitive citrus, this hardy evergreen forms a handsome tree and is a tough addition to most gardens.
