- Description
-
Swamp Cottonwood is a large deciduous tree in the willow family. It is found in riparian and low-lying wet areas in the Southeast. While it usually has a poor form, it can grow up to 70-90' tall with a trunk 2-3' in diameter in proper conditions.
The tiny seeds can only germinate in the presence of moisture and sandy soil. The downy coating lets them be carried long distances on the wind.
The soft, light wood is used for crates, baskets, and high-quality paper pulp. It has a tendency to warp as it dries if not given proper caution.
This plant is found at wet bottomlands.
