Black Poplar Overview

Populus nigra is commonly known by the names Black Poplar and Lombardy Poplar. It is a deciduous tree species from the Salicaceae family. It originates from Eurasia and has been introduced to many areas. Grows with a bushy habit, producing heart to triangle-shaped leaves with serrated margins. Young leaves may be lightly hairy. Rough bark is dark brown-black in colour, the stems brown, lumpy and textured. Black Poplar are not the commonest of trees, but some have been bred for garden use. Dioecious plants produce male and female flowers on individual plants. They are wind-pollinated, coloured red on male plants and yellow-green on female plants. After flowering, female plants may produce fluffy seedheads.
