Blue Pine
The Blue Pine (Pinus wallichiana) is a native of the Himalaya, Karakoram and Hindu Kush mountains, from eastern Afghanistan east to Yunnan in southwest China. This pine grows in foothills and mountain valleys, and is a tree from 30-50 m in height. It grows in a temperate climate with dry winters and wet summers.
The needles are in bundles of five and are 12-18 cm long, and often droop gracefully. The cones are long and slender, 16-32 cm, yellow-buff when mature, with thin scales; the seeds are 5-6 mm long with a 20-30 mm wing.
This pine is also called the Himalayan White Pine. In the past, it was known by the invalid Latin names "Pinus griffithii" or "Pinus excelsa".
