| Identification | Whorled Wood-aster has a distinctive look: the toothed and lanceolate leaves are rather crowded at mid-stem and appear to be whorled but in fact are alternate with very short internodes. The rather large heads are showy, with slender and often twisted or crooked white rays and yellow disks. The plant may grow to 2 feet tall, but often much shorter. Note that of the many genera that now contain NC's former Aster species, this is the only species moved into the genus Oclemena. | |
| Taxonomic Comments | Long treated as Aster acuminatus.
