Aspens typically grow in clusters, as they propagate through their root systems, creating large groves that can be interconnected. These trees thrive in a variety of environments, often preferring well-drained soils and sunny locations. Aspens are important for wildlife, providing habitat and food for various species, including birds and mammals. Their wood is lightweight and used in products like paper and furniture.
