Sweet white trillium is a perennial herb that blooms from late March to early May. The inflorescence is showy, and quite large compared to others in the genus. This plant is typically found on very rich soils of slopes and coves over mafic or calcareous rock, often in or near seepage areas.

Sweet white trillium is endemic to a small area in the southeastern United States. It is rare throughout its range making it especially vulnerable to land-use conversion and habitat fragmentation.
