Description
A hardwood tree, Populus nigra, of the willow family native to Europe. Classified as a black poplar because of its bark color, the English poplar is a medium to large sized deciduous tree reaching 20-30 m with trunks averaging 1.5 m. Poplar leaves are diamond shaped and green on both sides. The typical tree grows quickly and is very specifc to species and growing locations. In general, poplar produces a soft, lightweight wood that is easy to work. The yellowish white wood has a fine, uniform grain but it is prone to warping. It is primarily used for paneling, light construction, packing crates and paper pulp. A yellowish dye can be extracted from the fresh leaves of the poplar. On wool, it produces a brass color with a chrome mordant and a yellow-brown color with an alum mordant. The extract does not dye cotton.
