Black Poplar

About Black Poplar in Alberta

Black Poplar is a Eurasian poplar, not a native Alberta tree, and Alberta evidence is strongest for the Lombardy poplar line of this species rather than for broad-crowned pure Black Poplar specimens. The most important ARA point is naming clarity: in Alberta native-tree contexts, "black poplar" may also be used for balsam poplar, so the scientific name must be checked before interpreting a record. Heritage value in Alberta is most likely tied to planted Lombardy rows, shelterbelts, windbreaks, cemeteries, institutional plantings, and other historic designed landscapes.

Identification: Leaves are simple, alternate, broadly triangular to diamond-shaped, and finely serrated. Compared with some cottonwoods, true Populus nigra lacks the conspicuous petiole-apex glands typical of Populus deltoides. Leaf shape helps, but Alberta identification must also use crown form, planting context, and scientific-name confirmation.

Alberta range and habitat: True Populus nigra is not a native Alberta tree. No native Alberta wild distribution is confirmed for this species.
