Eurybia mirabilis

Eurybia mirabilis, commonly known as the bouquet aster or dwarf aster, is an herbaceous perennial in the family Asteraceae. It is endemic to the lower Piedmont of North Carolina and South Carolina in the southeastern United States. Within this small range it is found only infrequently, making it of conservation concern.
