Orange is the fruit of the Citrus sinensis citrus species in the Rutaceae family. It is also called sweet orange, to distinguish it from its Citrus aurantium, referred to as bitter orange.

Orange is a tree that can reach up to 12 meters, with elongated and fleshy leaves and white flowers. The shoots are always green, never reddish. The fruits are round and both the peel and the pulp are of the typical orange color. The peel is characterized by a slight roughness that has become a term of comparison even in totally different fields: we are talking, for example, of orange peel skin in cosmetics, or orange peel surfaces in construction.

The rest period of the orange is only three months, so it happens that the tree flourishes and bears fruit at the same time. The first fruits can be harvested in November (navelina), and the last ones in May - June (valencia late). An adult tree produces around 500 fruits a year. (Wikipedia)
