Navel oranges are medium to large in size with the trademark navel, or circular hole, on the blossom stem end. The medium-thick rind matures from green to bright orange and is smooth with pebbled texture due to many oil glands found across the surface. Underneath the outer layer of the rind, the white pith clings to the flesh, but is easily peeled and has a spongy texture. The pale yellow-orange flesh is juicy, tender, seedless, and divided into 10-12 segments by thin membranes. These oranges are aromatic, sweet, and contain a low-acidity which produces a balanced level of sweet, tangy, and tart flavors.
