One of the many woodland Symphyotrichum spp. This one is blue flowering, occurs with cordate foliage, leaf section is not offset cordate closer to the petiole like Symphyotrichum urophyllum, and this one is also not aggressively dentate like S. cordifolium or Euribia divaricatus; the Euribia spp. is called white wood aster too, so it may help the issue with coloration of flower. Instead what we have here is Symphyotrichum drummondii, or Drummond’s blue wood aster, and upland wood aster, known for karst preference or dry oak upland forest.
Here it’s along an semi exposed dolostone area with ferrous parental top soil (iron rich clay), growing in sympatry( together) with Solidago flexicaulis (Zig Zag goldenrods), at Clifty Falls State Park, IN.
