Orange (Citrus sinensis (L.)) is a fruit tree belonging to the Rutaceae family, whose fruit is the orange. It is an ancient hybrid, probably between pomelo and mandarin, but for centuries it has grown as an autonomous species and propagates by grafting and cutting. Orange is a tree that can grow up to 12 meters, with elongated and fleshy leaves and flowers candid. The shoots are always green, never reddish. The fruits are round and both the skin and the pulp are of the typical color from orange to red, depending on the variety. The peel is characterized by a slight roughness. The rest period of the orange is only three months, so it happens that the tree flourishes and bears fruit at the same time.
