Rich beech-maple, oak-hickory, mixed swamp and floodplain forests.
The very short filaments and long anthers usually make this species easily recognizable; the filaments are rarely as long as 4 mm. The petals may be white [f. flexipes], maroon [f. walpolei (Farw.) Fernald], intermediate in shade, or reddish basally and white terminally. Different color forms may be found growing together. The odor may apparently be either sweet or foul; this varies somewhat with the age of the flowers.
Forms with petal colors other than white are suspected to represent hybrid swarms derived from crossing with T. erectum.
