Poplars have strong root systems that help stabilize the tree and make them resistant to wind and storms. However, it is important to note that poplar trees can be invasive and their vigorous root systems may cause damage to underground structures such as pipes and sidewalks. Therefore, it is advisable to carefully consider their placement in the landscape.

Whether you’re planting them for their aesthetic appeal or their practical uses, these trees have a lot to offer. As a master gardener, I’ll walk you through the most popular types of poplar trees and share everything you need to know about them along with some pictures.
