Populus deltoides W. Bartram ex Marshall
Eastern Cottonwood, Carolina Poplar, Necklace Poplar, Alamo
Salicaceae (Willow Family)
USDA Symbol: PODE3
Eastern cottonwood is a large-canopied tree with upright limbs becoming arching at the tips creating a vase-shape outline. The deciduous tree grows to100 ft. or more with stout branches. Catkins appear before leaf emergence. Large, papery, toothed, triangular, medium-green leaves turn yellow in fall. Large tree with a massive trunk often forked into stout branches, and broad, open crown of spreading and slightly drooping branches. Pendulous clusters of flowers without petals in late March and early April. Seeds wind-borne on a tuft of cottony hairs.
The common name refers to the abundant cottony seeds; another name, "Necklace Poplar," alludes to the resemblance of the long, narrow line of seed capsules to a string of beads. Although short-lived, it is one of the fastest-growing native trees; on favorable sites in the Mississippi Valley, trees average 5' (1.5 m) in height growth annually with as much as 13' (4 m) the first year. Plains Cottonwood (ssp. monilifera [Ait.] Eckenwalder or var. occidentalis Rydb.), a western subspecies or variety, has slightly smaller leaves that are often broader than long and more coarsely toothed.

Soil Description: Moist soils. Sandy, Sandy Loam, Medium Loam, Clay Loam, Clay
Conditions Comments: Rapid growth, though short-lived as specimen trees. Tolerant of any (except for constantly waterlogged) soil, does best in deep, fertile, moist but well-drained soil. Take hardwood cuttings in winter. Catkins produce an abundance of (airborn) cotton in spring. Weak wood and brittle limbs create wind and ice problems for this fast grower. Susceptible to a number of cankers and borers. Female trees produce clouds of cottony seeds each spring that can be a temporary nuisance. Roots can be invasive. Adapts to a variety of soils. Tolerates saline, pollutants and a wide pH range.
