Description

Ditrysinia fructicosa is a monoecious shrub. It may reach a height between 1.5 and 2.5 meters.D. fructicosa's leaves are alternately arranged and range in shape from elliptic to lance-elliptic. They may reach a length of 3 to 7.5 centimeters and a width of 0.8 to 3.5 centimeters.

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. 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.
