Thuja koraiensis - Korean thuja

Rarely grown in the West, the Korean thuja is native to a small mountainous area of eastern Manchuria and to northern parts of the Korean peninsula. This slow-growing conical tree can reach over 10m in its native habitat but often remains shrubby in less favourable spots. Due to excessive forest clearance for agriculture, there are few reproductive trees left and the species is on the endangered list in its native area.
