poplar - Student Encyclopedia (Ages 11 and up) Quaking aspen, also known as trembling poplar (Populus tremuloides), is one of the most widely distributed trees in North America. It is known for its fluttering leaves and white bark marked with black scars. (Source:Poplars are rapid-growing but relatively short-lived trees. They are widely distributed throughout the northern temperate regions, ranging from North America through Eurasia and northern Africa. The leaves are alternate and oval or heart-shaped in outline, with finely to coarsely toothed margins (leaf edges). The leaves characteristically tremble in the breeze, because of their flat petioles (leaf stalks). In North America, aspens usually have nonsticky buds and smooth gray-to-green bark, whereas cottonwoods and balsam poplars have sticky buds and bark that is darker and deeply furrowed. Poplars are dioecious plants, meaning the male and female flowers grow on separate trees. The flowers bloom in drooping catkins (pendulous unisexual flower clusters) before the leaves emerge, to facilitate wind pollination. The fruits are small thick-walled capsules that contain many minute seeds clothed in cottony tufts of silky hairs. The seeds are often released in great quantities, and the fluffy seed hairs assist in wind dispersal. (Source:Two well-known poplar species of Eurasia are the white and black poplars.

Columnar black poplars are widely used in ornamental landscape plantings, particularly among the villas of Italy and elsewhere in southern Europe. White and black poplars are widely planted in the eastern United States and in Canada.
