Korean Pine
Korean pine is native to the far-eastern Russian Federation, China, Japan and Korea.  In the north of its range, it grows at moderate altitudes between 600-900 m. Cones are large and resinous, containing edible nuts commonly called Chinese pinenuts.

It is a member of the white pine group, Pinus subgenus Strobus, and like all members of that group, the leaves are in fascicles (bundles) of five, with a deciduous sheath. They are 7-13 cm long. Korean Pine cones are 8-17 cm long, green or purple before maturity, ripening brown about 18 months after pollination. The 14-18 mm long seeds have only a vestigial wing and are dispersed by Spotted Nutcrackers.

Korean Pine differs from the closely related Siberian Pine in having larger cones with reflexed scale tips, and longer needles. The seeds are extensively harvested and sold as pine nuts, particularly in northeastern China; it is the most widely traded pine nut in international commerce. Korean Pine is a popular ornamental tree in parks and large gardens where the climate is cold, such as eastern Canada and the northeastern states of the USA, giving steady though not fast growth on a wide range of sites. Hardy down to at about -50°C.   --From Wikipedia
