Tarocco is a medium-large to large blood orange variety with few to no seeds. Tarocco blood orange is one of the major blood orange varieties of the world. The distinctive color is a natural mutation and is due to the presence of anthocyanin, the same plant compound that is responsible for the color of pomegranates. The distinctive color requires a chilly winter to develop properly. Tarocco #7 is one of the most delicious blood orange varieties in the Citrus Variety Collection, although the rind of this blood orange gets very little to no coloration at all. The tree is vigorous, but only moderately productive.
