Lodgepole pine (Pinus contorta latifolia)

Native to the USA, this pine has dark green needles in pairs, often twisted. Its male flowers are very ornamental. The Indians of North America use this species of pine to build the pillars of the center of their hut. Its growth is regular in height and diameter, even under the most difficult conditions. It seems that it can be found in the Alpine arc from north to south, from east to west and from sub-alpine to hilly.
