Populus is a genus of trees and shrubs commonly known as poplars. These deciduous plants are part of the family Salicaceae and are found in various regions around the world. Poplars are known for their tall, straight trunks and broad leaves, which can turn vibrant colors in the fall. They grow quickly and are often used for timber, paper production, and as ornamental trees in landscaping. Populus species thrive in moist environments, often near rivers and wetlands. They play a crucial role in ecosystems by providing habitat for wildlife and helping to stabilize soil. Some well-known species include the Eastern Cottonwood and Balm of Gilead.
