    Eastern Cottonwood is a very common tree species growing in swamps, bottomlands, and near streams, creeks, rivers, ponds, and lakes from western New England down to northwest Florida into central Texas up to eastern South Dakota & central Minnesota & central Wisconsin, southern Michigan into areas of southeast Canada a little into the tip of Quebec. It has big shiny leaves that are sort of triangular with big, rounded teeth and about 3 to 6 inches long x 4 to 5 inches wide that get a pale yellow autumn color often with some brown spots. The young bark is smooth and creamy tan but it soon becomes smooth gray-brown and then all brown and deeply furrowed. It is very fast growing of about 3 to 5 feet/year and lives about 100 to 125 years. It is a very tough and adaptable tree to many soils. It is weak-wooded and drops lots of twigs and branches. It has a shallow, fibrous root system and is easy to transplant. This species is not really for residential neighborhoods, but it is fine as a large tree in a large area as parks. Some native plant nurseries sell it for naturalistic situations.
