Poplar (Populus spp.)

Family: Salicaceae

Flowering: March - April



The tree may reach up to 40 meters height. The simple leaves are lobed and alternately arranged on the branches. The trunk is gray and mostly smooth. The male and female inflorescences, growing before the leaves, are present on distinct plants. These inflorescences are both conical and hairy. The fruit is a capsule containing hairy seeds. Dispersed by the wind, these seeds often generate a white and downy layer on the ground.


The poplar is often planted lined on roadsides. It is also found in forests, or lonely in parks and gardens. This tree is well adapted to the conditions of our regions. Though it preferentially grows on well-drained soils, it is able to adapt to different soil types.


Its pollen is not a frequent cause of allergy. The amount of pollen present in the air is mostly limited, but high pollen production is cyclically observed every 3 to 8 years.
