Populus fremontii (Western Cottonwood)

Fast-growing, Populus fremontii (Western Cottonwood) is an upright-spreading deciduous tree with stout branches clad with heart-shaped, bright green leaves turning a lovely yellow in fall. On mature trees, the ash-gray bark is divided into thick, flattened ridges, separated by deep fissures. In early-mid spring, clusters of long drooping catkins appear on separate male and female trees. The female flowers give way to capsules that split open to release clouds of cottony seeds that can be a temporary nuisance. Roots can be invasive as Western Cottonwood develops an extensive root system that can buckle sidewalks and damage sewer lines.
