Citrus sinensis 'Moro' (Blood Orange)

Blood Orange, Moro Blood Orange, Citrus 'Moro'


A popular blood orange variety, Citrus sinensis 'Moro' is a medium-sized, evergreen tree prized for its medium to large, juicy oranges with deep, wine-colored flesh. Frequently borne in clusters, they are the most intensely colored of the blood oranges. Their color is due to a pigment (anthocyanin) not usually present in citrus but common in other red fruits and flowers. The fruit is low seeded, with a soft flesh that can become dark red to burgundy late in the season. Pleasantly flavored, it has a slightly sweet, floral fragrance and a sweet-tart taste with notes of cherries and raspberries. The fruit holds well on the tree, but develops an off-flavor if held too long. Highly ornamental, the tree is of moderate vigor with a round and somewhat spreading growth habit. This early season Italian variety is very productive, its fruit usually ripening in winter to early spring. Valued for their unique flavor, Moro oranges lend themselves to many culinary uses. Favored by chefs, they are the most common variety in the United States.
