Cottonwood refers to several species of trees in the genus Populus, particularly Populus deltoides and Populus angustifolia. These trees are known for their tall stature, broad leaves, and fluffy white seeds that resemble cotton, which is how they got their name. Cottonwoods thrive in moist environments, often found near rivers and wetlands. The wood of cottonwood trees is lightweight and soft, making it suitable for various uses, including furniture and paper production. Cottonwoods also play a vital role in their ecosystems, providing habitat and food for wildlife, and helping to stabilize soil along riverbanks.
