Poplars / Cottonwoods

Scientific Name: Populus
Genus: Populus
Family: Salicaceae

Poplars and cottonwoods have distinctive heart- or triangle-shaped leaves. They were once very popular trees to plant for erosion control, but they tend to cause problems in urban areas. The roots are shallow and wide-spreading and they can lift sidewalks or puncture sewer lines. The male trees produce abundant pollen that can cause allergies and the females produce clouds of fluffy white seeds that drift and fall like snow.
