Salvia (scarlet sage) is a long-season bloomer that doesn't quit. Once established it flowers steadily from late spring until frost, which makes it one of the more reliable season-long pollinator draws in the garden. The flowers themselves are narrow, upright spikes of tubular blooms, usually red, packed onto 1.5- to 3-foot plants.
