This is a complete contrast to the "normal" blue salvia varieties that we see in this area. Black and Blue is taller and will definitely spread faster and larger than the other Salvia varieties (May Night, etc.) Black & Blue has gorgeous cobalt blue with black blooms that emerge from black whorls along the tall flower spikes, rising from the lush, green, aromatic foliage. Excellent for adding dark, dramatic contrast to any garden. Sensational season-long, heat-loving color for sunny beds and borders. She will drop seeds within your garden and replant new plants. At maturity, this plant reaches 2' tall and 3' wide. Butterflies and Hummingbirds love this plant!
