Mocha is the flower or spandex of the Banana plant. The type that is commonly found in the market is the end portion of the spandex which is chopped off after the banana is formed. It is purple in color. The other variety is the larger and greener which is cut from the banana tree before any fruit has matured. The purple or green leaves of the spandex are inedible. Only the inner immature banana fruit is eaten and even then care must be taken to remove the stylus.
