Sabatia stellaris, with the common names Rose of Plymouth, Marsh Pink, Salt-marsh Pink, and Sea-pink; is a species of Sabatia. It has the Syn. Sabatia maculata (Benth.) Benth. & Hook.f., Sabatia palmeri Gray, Sabatia purpusii Brandeg., Sabatia simulata Britt.).
The plant is endemic to the Eastern United States, where it occurs on the Atlantic and Gulf coasts, from Massachusetts south to Florida and west to Louisiana. It is a halophyte, restricted to salt marsh habitats, where it is threatened by the invasive species Phragmites australis.
The leaves are arranged in opposite pairs, narrow to broad elliptic in shape, with narrow leaves in Florida, and broad leaves in New England; the change in leaf shape is clinal, and cannot be separated into discrete subspecies or varieties.
