Black Cottonwood (Populus trichocarpa)
Family: Salicaeae Common names: Balm cottonwood, Black cottonwood, Cottonwood, Poplar, Western balsam poplar Distributed in: United States (North America) Distribution overview: Distributed from latitude 62 degrees N in south Alaska, southward to southern California and eastward in the mountains to extreme south-weatern Alberta and Montana. It is also reported to grow locally in south-western North Dakota and northern Baja California. Black cottonwood often occurs in pure stands, and in association with willows, Red alder, Oregon ash, Bigleaf maple, Douglas-fir, Western red cedar, Western hemlock, Sitka spruce, Grand fir, Birch, Cherry, and hawthorn. It prefers moist to wet soils of valleys, mainly on stream banks and flood plains. It may also be found on upland slopes. The largest concentration of Black cottonwood tress is found in the satae of Washington, where it is ranked third in total volume behind Red alder (Anus rubra) and Bigleaf maple (Acer macrophylla). also grown in Great Britain, where it is considered as the fastest growing balsam tree. Common uses: Baskets, Boxes and crates, Brooders, Casks, Chairs, Chests, Concealed parts (Furniture), Core Stock, Decorative veneer, Desks, Dining-room furniture, Dowell pins, Dowells, Drawer sides, Drum sticks, Excelsior, Figured veneer, Fine furniture, Floor lamps, Food containers, Furniture , Furniture components, Furniture squares or stock, Hatracks, Jewelry box, Kitchen cabinets, Living-room suites, Musical instruments , Office furniture, Organ pipes, Packing cases, Pallets, Piano keys, Pianos , Plain veneer, Poultry coops, Pulp/Paper products, Pulpwood, Radio - stereo - TV cabinets, Rustic furniture, Veneer Environment profile: Widespread, abundant, and globally secure Tree size: Tree height is 20-30 m
Black cottonwood is reported to reach maturity as early as 60 years and will survive for at least 200 years.
