This Serpentine Aster is a small, delicate, fine-textured perennial growing wild mostly in the serpentine barrens of southeast Pennsylvania, northeast Maryland, Virginia, and North Carolina, and there is one population in non-serpentine soil in North Carolina. Serpentine soils are derived from serpentine rock that is a soft, greenish-gray rock full of a few elements toxic to plants as nickel and chromium with a large amount of manganese, and these soils are shallow and dry. The aster's leaves are tiny of about 1.5 inches long and it bears the tiny white flowers of 7 to 14 rays on a flower in late summer and early fall. It is a rare species.
