About
Pinus wallichiana is a coniferous evergreen tree native to the Himalaya, Karakoram and Hindu Kush mountains, from eastern Afghanistan east across northern Pakistan and north west India to Yunnan in southwest China. It grows in mountain valleys at altitudes of 1800–4300 m (rarely as low as 1200 m), reaching large sizes from 30–50 m (98–164 ft) in height. It favours a temperate climate with dry winters and wet summers. In Pashto, it is known as Nishtar.
This tree is often known as Bhutan pine, (not to be confused with the recently described Bhutan white pine, Pinus bhutanica, a closely related species). Other names include blue pine, Himalayan pine and Himalayan white pine.
How to grow it
The wood is moderately hard, durable and highly resinous. It is a good firewood but gives off a pungent resinous smoke. It is a commercial source of turpentine which is superior quality than that of P. roxburghii but is not produced so freely.
The tree became available through the European nursery trade in 1836, nine years after the Danish botanist Nathaniel Wallich first introduced seeds to England. It is a popular tree for planting in parks and large gardens, grown for its attractive foliage and large, decorative cones. It is also valued for its relatively high resistance to air pollution, tolerating this better than some other conifers.
