Populus nigra
The black poplar (Populus nigra), also known as the Lombardy poplar, is a species of deciduous tree in the willow family. Native to Europe, it has large, triangular, toothed leaves and tall, straight trunks which can grow up to 30m high. Its bark is dark gray and it produces attractive, velvety, gray-brown catkins in spring. It prefers sunny, moist, well-drained soils and can tolerate a variety of urban environments. Its wood is especially suited for carving and has been used extensively for its strength and lightness. Its showy foliage provides a beautiful backdrop for other plants.
