In the north of its range, it occurs from sea level to 1,000 m, while in the south of its range, it is a high altitude mountain tree, growing at 1,200-2,600 m altitude. It is readily identified by its combination of fairly short, blue-green leaves and orange-red bark. Leaves and cones, Poland.It is an evergreen coniferous tree growing up to 25 m in height and 1 m trunk diameter when mature, exceptionally to 3545 m tall and 1.7 m trunk diameter and on very productive sites (in Estonia, there are some 220 year old trees that are 46 metres tall in the forests of Jarvselja). The bark is thick, scaly dark grey-brown on the lower trunk, and thin, flaky and orange on the upper trunk and branches. The habit of the mature tree is distinctive due to its long, bare and straight trunk topped by a rounded or flat-topped mass of foliage. The lifespan is normally 150300 years, with the oldest recorded specimens (in Sweden) just over 700 years. The shoots are light brown, with a spirally arranged scale-like pattern. On mature trees the leaves ('needles') are a glaucous blue-green, often darker green to dark yellow-green in winter, 2.5...More: http: //booksllc.net/?id=18158
