Centennial kumquats are distinguished by their more rounded versus oval shape and their level of sweetness. In fact they are often simply referred to as the sweet kumquat. Centennial kumquats are entirely edible, rind, flesh and the occasional soft seeds. Centennial kumquats have a thick, smooth oily peel with aromatic citron fragrances and sweet flavor. The fruit's flesh is not overly juicy but still very flavorful and tart. Only by eating both the skin and flesh will its perfect sweet-tart flavor balance be experienced. The average size of a kumquat is about one inch in diameter. Suitable for growth in zones 9 and 10.
