The vegetation is Mediterranean in the north of the country. The forest (cork oaks, carob trees, pines …) and the maquis dominate all along the coast and on the flanks of the Tellien Atlas and different kinds of flowers and plants grow in gardens and orchards (jasmine, rosebush, geranium , rosemary …). Apart from alfa, very few plants grow on the highlands in the center of the country. In the oases of the Sahara, ingenious irrigation systems allow peasants to cultivate, apart from date palms, all kinds of fruits and vegetables in their plantations.
