What are five perennials that bloom all summer with almost no work?

Coreopsis, salvia, echinacea, black-eyed Susan, and Russian sage. Coreopsis blooms late spring to frost, needs full sun and any soil. Salvia attracts bees and butterflies, needs sun and well-drained soil. Echinacea blooms for months, handles drought. Black-eyed Susan blooms nonstop July to October. Russian sage is also low-maintenance.
