Populus alba, commonly known as the white poplar, is a deciduous tree species belonging to the family Salicaceae. It is native to regions of Europe and Western Asia and has been widely introduced to other parts of the world, including North America.
The white poplar typically reaches a height of 20-30 meters, with a broad and spreading crown. It has distinctive white or grayish bark that is smooth when the tree is young but becomes furrowed and rough with age. The leaves are alternate, simple, and triangular in shape, with a serrated margin. They are green on the upper surface and white or silvery on the undersides, which gives the tree its common name.
This tree is known for its adaptability to various soil types and environmental conditions. It prefers moist, well-draining soils and can tolerate both acidic and alkaline conditions. White poplars are often found in floodplains, riverbanks, and other wetland habitats. The tree produces catkins in spring, which are composed of male and female flowers. The female catkins mature into capsules that contain numerous tiny seeds with cottony hairs, facilitating wind dispersal.
White poplars are frequently cultivated for their ornamental value, as their grayish-white bark and silver leaves create an attractive visual impact in landscapes. They also provide shade and windbreaks due to their dense foliage. In addition, populus alba has been used for various purposes, such as timber production, papermaking, and herbal medicine.
Overall, populus alba is a versatile and aesthetically pleasing tree that is valued for its hardiness, adaptability, and decorative qualities.
