Black Poplar Tree
The Black Poplar (P. nigra, Linn.), of Europe and Asia, has become established in certain parts of the Eastern States, but it is now chiefly met with in its cultivated forms. Variety elegans is a dainty tree with small, bright, twinkling leaves and ruddy twigs and petioles. The following variety is much more extensively known, though it has less horticultural merit.
