Compact short plants produce their vibrant blue bloom spikes so closely set, they create a solid sea of color! This huge show graces the late spring and early summer garden, and then repeats later in the season, especially if spent blooms are cut. An incredibly low-maintenance plant, it tolerates dry or wet situations, is happy in most any soil, even a poor one, and is unfazed by heat and humidity. Plus, butterflies and hummingbirds love the intensely hued blooms! 15-18" tall and wide. Deer tend to avoid. Salvia nemorosa 'Blaukonigin'.
