 White Wood Aster
White Wood AsterSymphyotrichum divaricatum
This is a 2 ft. tall, loose, sprawling American-aster with clusters of   bright, white flowers. The tiny but numerous flowers have yellow centers and   white petals that fade to dark pink. Wiry, black, drooping stems may be 3 ft. in   length. Large, heart-shaped leaves become gradually smaller toward the top of   the plant. 
      
Comments: This white aster is a typical late summer-early   fall bloomer in open woodlands. Among the related species in the East, the   taller Bigleaf Aster (Eurybia macrophylla) has large, thick, rough leaves,   lavender flowers, and rough, glandular flower stalks. When very young, its   leaves may be cooked and eaten as greens. Both species used to be in the genus   Aster.
