In a Nutshell:
* This tree is widely grown in the Southwestern United States to produce Christmas Trees.
The Eldar pine is treated as a species (Pinus eldarica) by some authors, it is adapted to a drier climate with a summer rainfall peak. more...
* Introduced by the U.S. Department of Agriculture to the southwest U.S. because it tolerates dry winds and alkaline soils.
The Afghan pine prefers warmer temperatures than most of the Pinus genus. It thrives in U.S. Department of Agriculture hardiness zones 6 through 8, but can also grow in parts of zones 9, 10 and 11. This range encompasses most of the continental U.S. -- it covers southern states, like New Mexico and Alabama, as well as coastal states on both the Pacific and Atlantic shorelines. Afghan pines can grow in extremely arid climates, including the desert regions of Arizona and Texas. They grow best with full exposure to sunlight and can tolerate slight drought, temperature fluctuations and various soil conditions.
* Pinus eldarica is not native to the Americas or Europe, but originated in the warm and dry climates of western Asia, including areas of Asia Minor, the Middle East and land around the Caspian Sea. This species is one of the newest members of American forests. It was introduced to the U.S. in the middle of the 20th century and was not distributed until the 1960s. It has become established in various states and climate zones throughout the country, but it is not nearly as common as native pine species.
* The Afghan pine does have significant aesthetic value, thanks to its symmetrical growth pattern. It is particularly suitable for dry climates that cannot support fragile ornamental trees. Its relatively dense foliage also makes it a viable choice as a shade tree for lawns and open areas. more...
