Orange trees are small to medium-sized, evergreen trees which grow to a height of up to 10m. They develop fruits, like other citrus fruits, without cross-pollination. The fact that there are some 400 tasty varieties of oranges means that it is not always easy to decide which of this popular fruit to choose.
The orange belongs to the Citrus genus in the rue family (Rutaceae) and has existed for over 3000 years. Oranges originated in Southern China and in some countries, such as the Netherlands, their name in the local language actually means “Chinese apple”. Oranges are meanwhile grown in all warm countries - oranges bought in winter in Germany predominantly come from Spain, for example.
