Distribution & Occurrence
- South Carolina
Mixed pine oak-hemlock forests in ravines or along streams, with rosebay and Carolina rhododendron in the moister sites and lowbush blueberry in the drier sites; also in oak-beech forests.
|Georgia: Fewer than 12,000 plants in 6 populations are known. South Carolina: two populations are known, with fewer than 100 plants.|
Conservation, Ecology & Research
Potential pollinators that have been observed visiting Edna's trillium flowers include wasps, honeybees, small bees, and small flies; sap beetles may also be an effective pollinator (USFWS 1984).
Ednas trillium is not a vigorous competitor and will not survive in areas with a dense herbaceous layer; it is quickly overcome by exotic pest plants such as Japanese honeysuckle that invade following disturbance (Patrick et al. 1995).
