The female palms produce a very high amount of fruits. Some of them can provide more than 200 kilos a year. There are bunches of dates that can weigh over 12 kilos. The main producers of dates in the world are Saudi Arabia, (the emblem of this country contains a palm tree) Iran, Egypt and Iraq. Tunisia and Algeria export a lot to Europe.

The date palm has adapted well in America after having been exported in the nineteenth century by the Spanish colonizers. There are large fields planted in Mexico and California.

Spain is the most northerly date producer. The " Palmeral of Elche" (= the palm tree orchard of Elche) in the province of Alicante (Spain) is very-well known. It dates from the Arab colonization, when the city was surrounded by many date palms. In this way, palm trees could benefit an area where rainfall was very scarce.

This plantation hat its moment of maximum splendor in the eighteenth century when it contained more than 200,000 samples. In fact, it is the largest in Europe and has been named World Heritage by UNESCO.
