Wikipedia Abstract

Populus heterophylla, also known as downy poplar, swamp poplar and swamp cottonwood, is a large deciduous poplar belonging to Populus section Leucoides. It is found in wet bottomland forests, reaching a height of 100 feet (30 m) at full maturity and 50 feet (15 m) in 20 years. The swamp cottonwood is similar to the eastern cottonwood except the leaves are cordate (heart-shaped) instead of deltoid.
