Gorgeous cobalt blue with black blooms 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. An herbaceous perennial in mild winter regions; treat as an annual elsewhere.
