About

Eurybia paludosa, commonly known as the southern swamp aster or Savannah grass-leaved aster, is an herbaceous perennial in the family Asteraceae. It is native to the southeastern United States where it is confined to the Carolinas and the states of Georgia and Florida. It is generally confined to moist soils, though it can occasionally be found on sand hills along the coastal plain. The southern swamp aster is often confused with the closely related southern prairie aster (Eurybia hemispherica), though they do not occur in the same habitats or geographical areas. Its flower heads emerge in the late summer through fall and show deep lavender to purple rays with yellow centres.

Where it grows

Eurybia paludosa is confined to the U.S. states of North Carolina, South Carolina, Georgia and Florida. In Florida it is only known in Nassau County in the extreme northeast of the state. It is found in wet soils in habitats that include the edges of swamps and pools, moist savannas and low-lying pinelands. It is also encountered with much less frequency in drier habitats including atop small sand dunes along coastal plains and in open hammocks. As a principally low-lying species it is only found at elevations from sea-level to 100 metres.
