white poplar
Populus alba L.
Overview
- Appearance
- Populus alba is a tree that can grow 40-80 ft. (12.2-24.4 m) tall and 40-50 ft. (12.2-15.2 m) wide. The bark on young trees is smooth and greenish white becoming gray and wrinkled, as trees age.
- Foliage
- The leaves resemble maple leaves, but the topside of leaves are shiny, dark green while the underside is bright white and hairy. Leaves are 2-4 in. (5.1-10.2 cm) long.
- Flowers
- Flowers are inconspicuous and develop in slim, cylindrical flower clusters (catkins) before the leaves develop.
- Fruit
- Fruit are small, hairy seed pods that are spread by wind.
- Ecological Threat
- Branches are susceptible to breakage when under stress, such as heavy snow or ice. Trees produce prolific rootsprouts. Populus alba is native to Eurasia and grows best in full sun.
