Two areas of the Kingdom are producing crops not usually identified with Saudi Arabia. Tabuk, in the north of the country, has a growing industry producing flowers in greenhouses, almost half of which are exported, mainly to the Gulf Cooperation Council (GCC) states and to Europe. Fifteen varieties of flowers are cultivated, mostly carnations (with an annual production of 9.5 million), and roses (four million stems). Meanwhile, in the south of the country, farmers in Najran Province are cultivating around 40,000 tons of citrus fruits a year. The horticulture development research center set up there early in the 1980s has produced over a million seedlings that are distributed to farmers who want them.
