Eastern Cottonwood

Populus deltoides, the eastern cottonwood or necklace poplar, is a cottonwood poplar native to North America, growing throughout the eastern, central, and southwestern United States, the southernmost part of eastern Canada, and northeastern Mexico. Populus deltoides is a large tree growing to 20–60 m (65–195 ft) tall and with a trunk up to 2.8 m (9 ft 2 in) diameter, one of the largest North American hardwood trees. The bark is silvery-white, smooth or lightly fissured when young, becoming dark gray and deeply fissured on old trees. The twigs are grayish-yellow and stout, with large triangular leaf scars. The winter buds are slender, pointed, 1–2 centimetres (1⁄2–3⁄4 in) long, yellowish brown, and resinous. It is one of the fastest growing trees in North America. In Mississippi River bottoms, height growth of 10–15 feet (3–5 m) per year for a few years has been seen. Sustained height growth of 5-foot (1.5-meter) height growth and 1-inch (2.5-centimeter) diameter growth per year for 25 years is common.
