Fast-growing, Populus alba (White Poplar) is a wide-spreading, suckering, deciduous tree with a broad crown boasting an attractive foliage of 3-5 lobed leaves, up to 5 in. long (12 cm), lustrous dark green above and white and downy underneath. The fuzzy undersides make the tree sparkle when the breeze stirs the leaves, creating a beautiful two-toned effect.

Fast-growing, Populus alba (White Poplar) is a wide-spreading, suckering, deciduous tree with a broad crown boasting an attractive foliage of 3-5 lobed leaves, up to 5 in. long (12 cm), lustrous dark green above and white and downy underneath. The fuzzy undersides make the tree sparkle when the breeze stirs the leaves, creating a beautiful two-toned effect. Equally striking, the bark is very white and smooth when the tree is young, becoming darker and more furrowed with age. In spring, before the leaves emerge, small male and female flowers appear in separate catkins on separate male and female trees. The female flowers give way to capsules that split open to release clouds of cottony seeds. Roots can be invasive as White Poplar develops an extensive root system that may damage drains and foundations. The wood of White Poplar is fairly brittle and subject to breakage in storms. Grown for its very rapid growth as a specimen tree, it is equally useful for windbreaks.
