Eurybia chlorolepis, commonly known as the mountain wood aster, mountain aster, or Appalachian heartleaf aster, is a herbaceous perennial native to the southeastern United States. It is present only at relatively high elevations in the Appalachian mountains. Although it is not considered seriously threatened due to a large number of sites in some of its range, it is often locally endangered and possibly extirpated in the south of its range.
