Although actually a woody shrub, Bluebeard is usually cut back each spring to 6 inches and treated more like a perennial. Plants form a bushy, upright mound of silvery-green leaves, the fragrant sky-blue flowers forming on new wood in late summer and fall. Extremely attractive to butterflies! This American selection is outstanding both for the foliage and flowers. Choose a well-drained location in full sun. In mild winter areas, these are also excellent in tubs or mixed containers. Heat tolerant. Fairly drought tolerant, once established.
