‘Longwood Blue’ is ideal for a mixed or shrub border. It’s an attractive woody shrub up to 3 feet tall and 5 feet wide with silvery leaves and violet-blue flowers.. The flowers appear along the stems in late summer and early autumn.This plant is relatively drought tolerant and very heat tolerant. The shrub expands as branches that touch the ground form their own roots and may self-seed.
CareGrow in well-drained soil that is not overly rich. Trim back in spring to keep rounded clump form. Cut back to 3-inch stems in late winter to promote vigorous branching growth. May need to be hard pruned in spring in areas with severe winters.
Propagation Separate rooted stems from parent plant and transplant in early spring. Root cuttings in late spring or early summer.
