CRITIQUE
Eastern cottonwood is a large, fast-growing tree found growing along streams, rivers, and lowland areas. It is native to eastern North America through the Midwest and Chicago region. Due to its large size, weak wood, and penetrating roots, it is best used on large properties away from residential areas.
