The term “cottonwood” refers to certain species of trees in the genus Populus, particularly Populus deltoides (eastern cottonwood) and Populus angustifolia (narrowleaf cottonwood). These trees are known for their tall stature, broad leaves, and fluffy seed fibers that resemble cotton, which are released in the spring. Cottonwoods are commonly found in North America and are often associated with moist habitats, such as riverbanks and floodplains. They are valued for their fast growth and are sometimes used for timber and landscaping.
