Small but abundant flowers (to 1" across) with deep lavender to blue rays and yellow centers appear in flat-topped clusters in autumn. A late blooming aster that still looks fresh at time of first frost. Attractive to butterflies.
Genus name comes from the Latin word aster meaning star for the shape of the flowers.
