The Blue Pine (Pinus wallichiana) is a pin native to the Himalaya, Karakoram and Hindu Kush mountains, from eastern Afghanistan east across northern India to Yunnan in southwest China. It grows at high altitudes in mountain valleys at altitudes of 1800-4300 m (rarely as low as 1200 m), and is a tree from 30-50 m in height. It grows in a temperate climate with dry winters and wet summers.
This pine is also called the Himalayan White Pine. It is also often known as 'Bhutan Pine', a name which can cause confusion with the more recently-described Pinus bhutanica, a closely related species.
