Narrative
Native to North America, this deciduous tree has a native range that covers the Atlantic coastal plain concentrated in the Carolinas and also along the Mississippi and Ohio Rivers along with various, tiny disjunct populations widely scattered across the southeast U.S. (Little, 1971). As an obligate wetland plant, the soils that this species inhabits is typically heavy clay (ranging 24 to 65%) and slightly acidic (soil pH ranges from 4.6 to 5.9) (Johnson 1990). Typical habitat is bottomlands/floodplains that generally have standing, shallow water. Sites that are often too wet for P. deltoides are suitable for P. heterophylla. Swamp Cottonwood can reach 10-20 meters in height and generally has an upright, rounded form. Broadly ovate leaves are rather large reaching up to 25 cm in length and nearly 15 cm wide with abaxial surfaces usually pubescent to partially glabrate. As with many other species in Salicaceae, P. heterophylla is dioecious with staminate and pistillate catkins appearing in early spring and reaching up to 10 and 15 cm in length, respectively. Seeds are dispersed in spring through early summer. Swamp Cottonwood is distinguishable from other Populus largely due to the distinctly cordate leaf bases and distinctive orange-brown pith in young twigs (McMaster 2003). Ornamental characteristics include golden yellow fall color. This taxon is essentially non-existent in the nursery trade and extremely rare in botanical garden and arboretum collections. Due to this species ability to grow in anaerobic, soils heavy in clay, this species may perform well in the typical urban landscape. Its potential to withstand extreme, drought despite being an obligate wetland plant may be similar to that found in Taxodium distichum. Genetics of this accession were collected in southern Indiana. Specimens sampled in nature were approximately 40-50' in height and were clonally (vegetative) spreading by rhizomes.

NC7 Trials Plant Description
Actions
  • Description Of NC7 Ornamental Trials: The NC-7 Regional Ornamental Plant Trials, began in 1954 through the efforts of a small group of dedicated horticulturists under the leadership of Professor S.A. McCrory of South Dakota State College (now University). The north central United States is a region of climatic extremes, and many parts of the region have alkaline soils that developed under grasslands. Because of these conditions, the diversity found in commercially available woody plants adapted to the area is less than that found in most other parts of our nation. The NC-7 Regional Ornamental Plant Trials were started with the ultimate goal of expanding the range of useful plants in the nursery trade. The emphasis in this program has been placed on detailed, long-term evaluations at a broad range of sites rather than on promotion of new plants. The NC-7 Trials rely on a network of horticultural cooperators located at sites scattered across the Central United States. Cooperators establish plantings, observe and evaluate the plants through the seasons, and prepare performance reports one, five, and ten years after planting. These reports are sent to the North Central Regional Plant Introduction Station (NCRPIS) in Ames, Iowa where they are recorded. Because of the broad range of environments found among the trial sites, it is unusual for any particular trial plant to perform well at a majority of the sites, making system-wide releases difficult. However, when plants perform especially well at sites, the NCRPIS Horticulturist assists trial site cooperators in introducing the new plants, with any official releases initiated through the cooperators' institutions rather than through the Plant Introduction Station.
