The Cara Cara Navel Orange tree, also known as the red-fleshed navel orange, is a seedless and sweet citrus fruit that is low in acid. It is a medium-sized orange with little to no pit, making it easy to separate from the rind. Believed to have originated as a spontaneous bud mutation on a Washington navel orange tree, this early-to-midseason fruit is a popular choice for those looking for a unique and flavorful orange variety.
