National Tree
The national tree of the DPRK is pine.
It is an evergreen conifer of the family Pinaceae which grows on a vast area below 800m above sea level except the northern highlands of Korea.
It is 20-40m tall and 60cm in diameter.
Its furrowed bark is reddish brown or dark brown.
Buds, cylindrical or elliptical in shape, appear in winter, three or four or even six at the end of a branch.
Bundles of leaves come out in pairs at the end of a sprig or by threes in some young trees and well-grown trees. The leaves are 7-12cm long each, the longest 14cm.
Evergreen and viable, the pine tree symbolizes the unflinching spirit of the Korean people.
