About

Populus deltoides, the eastern cottonwood or necklace poplar, is a species of cottonwood poplar native to North America, growing throughout the eastern, central, and southwestern United States as well as the southern Canadian prairies, the southernmost part of eastern Canada, and northeastern Mexico.

Where it grows

The range of the eastern cottonwood is very large, stretching from southwestern Mexico northwards to the southern provinces of Canada and from New Hampshire to Oregon. In Mexico, it is mainly present as subspecies wislizeni and it is native only to the state of Jalisco in the southwest. In the northwest, it only grows in the state of Sonora. In contrast, it is found in about half the states of northeastern Mexico including Aguascalientes, Coahuila, Chihuahua, Durango, Nuevo León, and Zacatecas. It is also present in the Gulf Coast state of Veracruz.

Uses

The wood of eastern cottonwood is typical of the Populus family in its softness, weighing just 0.45 g/cm3 (28 pounds per cubic foot). It is utilized for things like plywood and interior parts of furniture.
