Appearing as masses of solid royal purple from late summer into fall, these asters form wonderfully compact, rounded mounds. They are terrific accents for fall blooming grasses and the changing colors of the trees. Try cutting a few of the tall, flowering stems for a fresh bouquet--bring the outdoors in.
To promote dense growth that is less likely to flop, pinch plants back from late spring until July 4th.
Trim to the ground in late fall after several frosts.
