Habitat This species is considered to be facultative to facultative wetland by the United States Department of Agriculture.
In general, D. fructicosa may be found in habitats that are mostly shaded and are considered moist-to-wet, such as swampy forests.Weakley, A. S. (2015). Flora of the Southern and Mid-Atlantic States. Chapel Hill, NC, University of North Carolina Herbarium. However, due to its facultative nature, this species has been observed to occur in other types of habitats, such as: within a mesic woodland, within a floodplain forest, and on limestone bluffs.Florida State University Robert K.
