HEART-LEAVED ASTER, BLUE WOOD ASTER
Aster cordifolius of Michigan Flora.
Beech-maple, oak-hickory, and swamps (as on floodplains), especially at borders and clearings; thickets, sometimes weedy in habit in urban areas. The rays are usually as short as in S. urophyllum, but are almost always blue or purple and the inflorescence is more open, the phyllaries merely acute (with rather clear diamond-shaped green tips on the midvein), and the leaves with more deeply toothed and cordate blades on petioles wingless or nearly so.
