Poplar is a type of tree known for its tall, straight trunk and fast growth. These trees are often found in parks and along roadsides, providing shade and beauty to the landscape. Poplars can grow quite large, reaching heights of up to 100 feet, and their leaves are typically heart-shaped and vibrant green. There are several species of poplar, including the Eastern Cottonwood and Balm of Gilead. These trees are also valued for their wood, which is lightweight and used in making furniture and paper. Additionally, poplars play a role in improving air quality by absorbing carbon dioxide.
