This poplar was developed by the UNAL (Union Allumettière) in order to obtain a fast-growing clone for wood production (matches). It is a strong grower and produces a great deal of wood at a young age. But the quality of the wood is less than that of other 'UNAL' clones. It forms a fine columnar shape with a good ascending head. It hardly suffers from crown break. The bark starts off smooth but flakes off at a greater age. The dark green leaves have a silver-white underside. 'Columbia River' bears flowers in the form of male catkins. Sensitive to wind and very sensitive to sea wind and rust. Used in forestry and as a solitary in parks and public gardens. Winter hardiness zone: 5a
