Cottonwoods are large deciduous trees belonging to the genus Populus, commonly found in North America. They thrive in moist environments, often near rivers and wetlands, and can grow up to 100 feet tall. Their broad, triangular leaves turn bright yellow in the fall, adding vibrant color to the landscape. These trees are known for their distinctive white bark and fluffy, cotton-like seeds that disperse in the wind during late spring. Cottonwoods provide important habitat for various wildlife species and are often used in landscaping for their shade and aesthetic appeal.
