The grapefruit is a variety of tree that resulted from crossing the largest lemon tree with the Chinese orange tree in the Antilles.
It was brought from Asia, where it was originally grown, by Captain Shaddock in the second half of the 17th century. It spread from England to continental Europe.
It is not grown in our country, it is imported, for example, from Spain or Morocco. It is also grown in Israel or the USA.
