It is native to the southwestern United States and northern Mexico, and is known for its fast growth rate and its ability to survive in harsh climates. The second type of Cottonwood is the POPLAR, which is a species of tree in the willow family. It is native to Europe, Asia, and North America, and is known for its tall, straight trunk and its broad, heart-shaped leaves. Both types of Cottonwood are popular for their use in landscaping and as a source of wood for furniture and other products.
