Report an issue with this species

Populus is a genus of fast-growing deciduous trees, commonly known as poplar, aspen, and cottonwood, found across the Northern Hemisphere. They are noted for their variable leaf shapes and some species, like the white poplar, feature striking white bark. Many species thrive in riparian zones and show tolerance to cold and some drought conditions, making them adaptable for urban planting.
