About plant names...

Small white aster is native to eastern North America.

Identification: Plants are 12-35" (30-90 cm) tall. Leaves are alternate, sometimes toothed, unlobed, ⅛-1½" (5-40 mm) × ⅛-½" (5-15 mm) in size. Numerous flowers are clustered along long stems in racemes. The central disk is yellowish, aging to a pinkish color. Ray flowers are white to pink, with 16-20 rays, rarely as few as 12. Flowers are about ½" (1.3 cm) across, and they tend to cluster along one side of each branch. They appear from August to October.
