Densely packed clusters of deep purplish-red flowers provide outstanding color in the garden from late summer into fall. They make a terrific accent to fall blooming grasses and the changing colors of the trees. 'Alert' has an especially compact habit and the flowers are great for cutting. This species is valued for its compact growth habit, rich flower color, and floriferous tendencies. It is native to North America.

Growing & Maintenance Tips:

This species performs best in rich, evenly moist soil and full sun. Give them lots of room to grow; good air circulation will help to prevent powdery mildew. To maintain their health and vigor, divide plants every couple of years in the spring.
