Asteraceae or Sunflower Family
Herb with large clusters of small flowers. Each
flower is really a head 1/2 to 5/8 inch wide containing a center
of tiny yellow disc flowers surrounded by about a half dozen
pale blue-violet ray flowers. Leaves are heart-shaped to
arrowhead-shaped, toothed, with a winged stalk and a smooth,
almost greasy surface. Blooms in late fall.
Native. Partially open woods and hillsides in the Park.
There are many asters in the Park, and they are hard to tell
apart; however, Lowry's aster is fairly distinctive because of
its more-or-less heart-shaped leaves with winged stalks.
Wavy-leaved aster (S. undulatum) also has a
winged stalk and similar leaves, but the wing on the stalk is
conspicuously widened at the base where the stalk joins the
stem. Heart-leaved aster (S. cordifolium) has
similar flowers and leaves, but the leafstalks are not winged. Schreber's aster (Eurybia schreberi) also has simlar leaves, but the flowers are white and the leafstalks not winged
