North Korea has a temperate but varied climate with warm summers and winters that are cold and dry. The landscape rises from the sea to the height of the Paektu-san Mountain, 9,000 feet above sea level. This variety of terrain gives rise to a rich assortment of native plants, which give the North Korean landscape its own distinctive appearance.
