Description

Frost Aster is a herbaceous perennial that may grow 4 to 5 feet tall. It is weedy in most of the eastern U.S.  The leaves are alternate with a smooth margin. Both the stem and leaves are covered with fine hairs. The roots are fibrous and form a woody crown. Small, white flowers with a yellow center first mature in late summer and persist into late fall. The herb produces a dry seed (achene) that matures in late fall.  Grows well in dry conditions and in rocky or sandy soils.
