Peuplier

Le peuplier est le nom commun du genre botanique Populus, un groupe d’arbres de la famille des Salicacées.

Poplar is the common name for the genus Populus, a group of trees in the willow family (Salicaceae). These are generally large, fast-growing deciduous trees found mainly in temperate and cold regions of the Northern Hemisphere. In Canada, several species of Populus are native, including poplars found in forests and riparian areas.

Classification and description

Populus is a genus of trees in the family Salicaceae, closely related to willows. Poplars are generally deciduous trees with an upright growth habit that can reach significant heights—typically 20 to 40 metres depending on the species.

Distribution and habitat

Poplars are mainly associated with temperate and cold regions of the Northern Hemisphere, including Europe, Asia, and North America. They often grow in moist soils near rivers, stream banks, and marshes, and are frequently found in wetlands and valley bottoms.

Species and hybrids

The genus contains approximately 25 to 40 species, depending on the source. Well-known species include black poplar (Populus nigra), white poplar (Populus alba), and trembling aspen (Populus tremuloides). Hybrids and cultivars are widely planted, especially in Europe.

Human uses

Poplars are planted for roadside alignment, ornamental purposes, windbreaks, and timber production. Some species are also studied for their ability to absorb certain pollutants such as trichloroethylene.
