The mandarin is a citrus fruit that is globular in shape and slightly depressed at the base. It has a smooth peel and measures approximately 4.7 cm. Native to Asia, the mandarin grows on a small, prickly tree and is commonly propagated through asexual reproduction methods like grafting. Mandarins are harvested from March through August, with the fruit taking 4 to 5 months to fully develop, and are a good source of vitamin C.
