Flowers of the Aromatic aster appear in fall (September-November) and are composite with purple to violet ray flowers along their edges and yellow disk flowers within the center. Ray flowers usually have a petal which radiates outward from the composite flower's center. The oblong leaves are .5 to 3 inches long and alternate, progressing singly up the stem.
Aromatic aster is an adaptable, easy to grow ground cover for dry, sunny locations. It creates showy mounds of blooms in fall and is excellent for native landscape gardens. Asters will grow on disturbed sites and can be used for wildlife habitat restoration. A tea made from the roots of asters has been used to treat fevers.
